Adjustment work of the front suspension of the VAZ 2107. How to properly tune and strengthen the suspension of VAZ cars

The desire for tuning begins with discomfort, when everything is as it should be, but something is still wrong. And the rest of the actions already depend on the driver himself - someone has enough instrument clusters with the original design of the scales, and someone wants to upgrade almost every element of the vehicle.

Due to the high demand for tuning certain elements, the shops simply overflowed with a variety of accessories, auto workshops had to recruit specialists in tuning of varying complexity, and thematic publications appeared on the shelves of kiosks.

Our article will not be replete with giant pictures, since the emphasis is on information, not images.

Every motorist wants his vehicle to be perfect in all aspects, from interior elements to the engine.

For the most part, the improvement of the vehicle stops at the installation of aerodynamic elements, sports locks, mufflers, steering wheel and seats. There is nothing shameful in striving to see your vehicle not as the manufacturer intended it to be. It all depends on the tastes of each person. However, it is important to know when to stop, since an excessive passion for tuning makes the car look somewhat strange and incomprehensible.

There are other tuning enthusiasts who dream of improving the engine. They just simply torment car engines, expanding the working volumes, the compression level, modernizing the crankshaft and timing, performing chip tuning, installing nitro and other elements. But here it’s already worth thinking about, because such methods that increase the power of the vehicle require an increase in responsibility for the owner in the form of additional obligations.

The reason is that any, even a weak vehicle, is dangerous in itself, and if the car just has huge power that is not comparable to the braking dynamics, then it’s already worth considering. How can you protect yourself, and how to protect others from possible dangers? It is wrong to believe that a motorist who decides to increase the power of the motor will limit himself in the speed of movement, because such operations are performed to squeeze all the forces out of the motor. The speed will increase, and any serial unit is simply unable to cope with the assigned tasks. The suspension and its average characteristics are completely unsuitable for this business, the brakes even reach a critical operating mode. Standard tires are not able to provide the car with the filigree that is needed for intensive handling at high speed.

However, in general, the modernization of the suspension brings with it such advantages: a decrease in body turns during cornering, longitudinal and transverse rocking and a number of other nuances almost completely disappear. In addition, the suspension as a whole becomes very stable.

tuning problems

When on a slippery road a stream of cars is overtaken by a dull-toned car with a raised stern, ten minutes later you have to watch the work of rescuers who get a vehicle that has fallen into reinforced concrete fenders. After this, involuntarily, I want to ask a rather obvious question. The old adage that you should not pick up a lot of speed without proper confidence will be relevant at all times. In such cases, it remains to advise a banal rule - never exceed the speed limit, contrary to your desires.

A professionally sharpened tool requires a confident and firm hand. Therefore, the approach to the expedient exploitation of all the power reserves of an extreme vehicle should be as serious as the attitude of doctors to their work in the course of operations. A quality scalpel will become useless and dangerous in the hands of an amateur who has never opened an anatomy book. Because professional driving is much more important than a boosted engine, reference suspension and modified brakes.

For each driver, such traits as a calm character and patience with other drivers or pedestrians are important. You don’t need to turn on the signal for pedestrians with or without reason, you don’t need to scare them by picking up speed after the green light is on. You also need to be more sensitive to drivers for whom driving a car can lead to stress. Old women, children, young mothers also need to be treated more condescendingly. Of course, after a hectic day, it's easy to forget about it, and you want them all to move faster. But still, you need to understand that city streets are not the best place for rapid acceleration.

Before you get behind the wheel of a vehicle, it is worth considering such nuances: will the gasket between the steering wheel and the seat withstand the power that the head gasket can handle? If you cannot answer yes to this question, then it is better not to use the full potential of the machine in one fell swoop. Well, if ambitions are overflowing, it makes sense to visit a school focused on extreme driving. Given the situation on domestic roads, it will be very, very useful. At the end of their studies, few drivers will step on the gas without thinking everything through in advance. After all, a person tends to acquire not only specific skills, his attitude to driving a car as a whole changes as a phenomenon.

Before proceeding with the finalization of the vehicle, it is important to know specifically what it will be, how radical the changes will be, and what they will bring with them. It's one thing to put on pedal pads, a chrome-plated gear knob, sports seats and a steering wheel. But intervention in the design of the motor, suspension, brakes and body is a completely different matter. Although both branches fall under the same category.

It is also important which vehicle will be modified. It is possible to make sports vehicles out of rare cars, but there is practically no point in this. Putting a powerful engine on a rarity is only half the battle, in order to realize its potential without harming yourself and others, you will need to revise the design of the vehicle as such. True fans of this activity, of course, no one can stop, but for an ordinary motorist, this idea will seem difficult to implement and hard on the pocket. Therefore, the choice must be final and complex. A process such as suspension tuning requires compliance with a certain regular sequence. First of all, you need to do everything in a logical way, due to which the transport will acquire a new character, the degree of rigidity of which rests on the wishes of the owner.

It is also worth paying attention to the brake system. It makes sense to work on the reserve.

In the future, proceed to the design of the motor. At this point, an extensive choice is provided for activities: from multifaceted improvements to the standard motor and ending with the installation of a more powerful option. It also depends on the tastes and priorities of the owner.

Having received an engine with other characteristics, it becomes necessary to get an engine aggregated with a transmission in order to get the most out of it. As you know, a standard box in combination with a GPU with an updated engine will interfere with the smooth operation of the system, so a selection of rows and gear ratios will be required.

Alternatively, you can calculate in advance, starting from the power of the motor, calculate the necessary transmission and braking parameters. Having decided on the operating conditions of the vehicle, you need to start selecting the optimal suspension characteristics, including wheels and tires.

Having dealt with the chassis, you can take on the exterior and interior decorations. There is also an extensive selection: unique lighting devices, aerodynamic solutions, image application and other interesting things. Changes to the interior can also hardly be called something incredibly complex - additional devices, sports seats and a steering wheel, various linings and controls, floor mats, as well as many other elements that give the car individuality.

The first stage of suspension modernization

People who have always dreamed of unlimited freedom have always been attracted by the idea of ​​long-distance travel. However, there are many places where you can’t go on foot, so the man had to tame the horses. Traveling alone proved dangerous and boring, and the poor artiodactyl was unable to carry more than one or two people on his back. And this is not to mention the road belongings in - that's why the idea of ​​\u200b\u200bthe wagon came to people. In between admiring the beauties of the surrounding landscapes, people were increasingly thinking about the comfort of travel, which was the reason for the appearance of a leather belt. The belt was replaced with wooden springs. But then they were also supplanted by more practical metal variations.

Many years later, horses were replaced by steam engines and the first engines.

The speed increased more and more, just as the demands on the vehicles themselves and the drivers increased. Safety, handling, ride, comfort and durability were the main factors. It required a complete revision of not only the design features of the suspension, but also the vehicle itself.

Suspension elements can be divided into: basic and additional. The main features are divided into steel products, gas and pneumatic elements, rubber, and plastic products. Their task is to hold the body in a specific position and ensure the elastic interaction of the vehicle with the road.

Additional elements include hinges connecting elements of a movable type in a suspension with a body. They are necessary to suppress oscillations and vibrations in the high frequency range.

If we talk about specific elements - springs, then they are divided into linear and progressive. In the first case, the spring stiffness changes in proportion to changes in length. These coil-type coil springs with a fixed pitch and bar thickness are designed for safe and extremely comfortable driving on a flat road.

In the second case, the spring stiffness changes regardless of changes in length. There are cylindrical shapes with variable pitch. They got their name due to a significant increase in stiffness during the compression process, avoiding holes and increasing the controllability of the vehicle.

It is also important to note the composite elastic elements, consisting of a pair of springs of different stiffness. They are separated by a special washer with the required level of elasticity or rigidity.

This option will reduce the vibration from a small fluctuation, due to the work of the elastic element of a small rod diameter and with a small step. Thanks to the second, stiffer spring, suspension holes are excluded in case of large damages on the road. As a result, the vehicle will receive good handling without sacrificing comfort.

shock absorbers

These elements are necessary in order to dampen body vibrations caused by road irregularities or inertial forces. Prevent vibrations of wheels, tires, wheel brakes, axles, axles, beams, hubs, and levers in relation to the body.

It is the efficiency of its workflow that affects comfort and safety, since in addition to reducing vibrations, its tasks include ensuring the reliability of contact between the wheels and the roadway.

The most common in modern suspensions are hydraulic and hydropneumatic shock absorbers, characterized by reliability, efficiency and manufacturability.

Their workflow involves converting a specific amount of kinetic vibrational energy into heat and dissipating heat. The amount of this energy depends on the mass of the vehicle, the spring stiffness and the frequency of vibrations. According to the principle of operation, they are based on the viscosity and compressibility of the liquid.

Shock absorbers can be divided into three types:

• Two-pipe hydraulic type solutions.
• Two-pipe hydropneumatic type solutions.
• One-pipe hydropneumatic type solutions.

If we talk about twin-tube pneumatic shock absorbers, then they have long become classic representatives of the family of hydraulic variations.

Two-pipe variations are characterized by the correspondence of the axes of the cylinders. The outer cylinder is called the reservoir, while the inner one has no other name. The cylinder contains a movable piston on which a bypass type valve is mounted. The lower part of the cylinder houses the bypass and compression valve, each of which was mounted in a separate housing. The cylinder is filled to its full volume with shock-absorbing liquid, the reservoir is only two-thirds, and the free space above the liquid is filled with air.

The damping process is carried out due to the hydraulic resistance provided by water when circulating through the valve system. The resistance, as well as the level of stiffness, are regulated by the aforementioned valves. The bypass valve allows fluid to flow in a specific direction.

In the process of shock absorber compression, water flows from the area under the piston to the area above the piston, and the volumes of liquid displaced by the parts of the incoming cylinder rod enter the reservoir from the outside. During release, the process is reversed.

It is worth dwelling in detail on a single-tube hydropneumatic shock absorber, commonly referred to as a "gas" shock absorber.

According to the principle of operation, it is similar to the two-pipe version: damping is performed due to the passage of fluid through calibrated compression and rebound valves. In this case, each valve is located on the piston, and the only pipe plays the role of both the body and the cylinder, therefore there is no reservoir as such. Now let's talk about physics. A liquid cannot be compressed, but in the case of a gas, everything is different - it can be compressed. This property was used by designers in the process of developing elements. They placed a separating piston at the bottom of the cylinder, and also pumped neutral nitrogen into the resulting volumes. As a result, the volumes of liquids displaced by the piston during the compression process are compensated by the compressible gas, which is located below the separating piston.

Recently, they have been trying to introduce, and in some cases have already commercially introduced shock absorbers controlled by electronic technology. In addition, systems are operated with a half-active control type, due to which the shock absorber is adjusted based on the speed of the vehicle.

Designs used

As you know, there is always something to strive for, even if the path to striving is not always obvious.

Therefore, each new technical solution surprises with its verified complexity or simplicity, however, both categories prioritize the modernization of the qualities of the vehicle. We will not be able to study each of the available pendants, therefore it is worth dwelling on the most famous ones.

It is important to note that suspensions are divided into two main types: dependent and independent. The former are used on trucks and heavy off-road vehicles, therefore they are not the cornerstone of the article. Well, the independent type is the most appropriate for this article, since it is used in cars.

The most common designs of independent rear axle suspension with longitudinal, transverse or oblique levers.

Front and rear axles can be used with MacPherson strut, upper and lower A-arms and slanting arms.

All of them are characterized by a variety of kinematic possibilities, as well as pros and cons, which make little sense to focus on. But in the case of general system requirements, it is better to remember.

Everyone knows that the characteristics of the suspension are directly related to the various parameters of specific parts and their interaction. Manufacturers of serial vehicles always make a choice in favor of average options. No one will allow you to reduce the level of security for the sake of comfort, and the reputation of such actions will be damaged. At the same time, cutting comfort for the sake of safety is also a highly irrational decision.

Therefore, manufacturers are trying to find a certain compromise that can satisfy the average consumer.

If we talk about the topic of requirements for ordinary transport, then we will not touch on them and will turn directly to the topic under consideration.

To obtain the required return, it will be necessary to replace the characteristics of the elements of the elastic and damping type. It is worth starting with elastic elements.

The softness of the springs and the large suspension travel serve as the forerunner to a high ride smoothness, sufficient freedom of body longitudinal oscillations and acceptable contact of the wheels with the road surface. However, there is one important drawback regarding the softness of the spring.

This factor is the cause of large overweight of the body when turning and a decrease in the ability of the tires to respond to side-type forces. In other words, when cornering, the vehicle will deviate from the planned trajectory, making the speed pass very problematic. It follows that fast driving requires a suspension with high stiffness and short travel.

How can this be done? The answer is quite simple - by installing modified springs and shock absorbers. In addition, you can look at progressive springs, which is useful if you want to lower the vehicle's ground clearance.

In terms of damping solutions, dampers with rigidity contribute to excellent wheel-to-road contact, with little loss in smoothness.

You can talk about the advantages of shock absorbers and springs for a long time, but it is worth reducing the unsprung masses. That is the purpose of light alloy and forged wheels. Tires are also worth noting, because high-type profile rubber can negate almost any transformation in the suspension, regardless of its stiffness.

First of all, this is a decrease in body roll during cornering, longitudinal and transverse rocking and a number of other nuances almost completely disappear. In addition, the suspension as a whole becomes very stable.

In addition, the vehicle will become more responsive to one or another turn of the steering wheel, having lost the pause characteristic of stock variations when changing lanes, and sharper reactions will dominate in habits. It is also worth noting that the clearance will be reduced, thereby reminiscent of sports cars

Possible problems

It is worth remembering that an increased level of stiffness of the suspension elements will not have the most desirable effect on the body: dynamic loads to which power elements are susceptible will be increased, the body will be more loaded with vibration. Since when hitting an uneven surface, the same amount of energy is extinguished as in the case of a soft serial spring and shock absorbers in suspensions with a long but shorter stroke, and this feature helps to reduce the life of the body, contributing to premature destruction of ball bearings, hinges, motor mounts.

With a significantly reduced clearance, it is not recommended to meddle on broken country roads for obvious reasons. And in urban areas, you can accidentally catch on something with the lower part of the bumper or suspension arm. At best, these will be small stones.

However, the clearance issue is not as scary as it might seem. Many companies involved in the sale of elements for the element in question make kits that include shock absorbers and springs with pre-selected characteristics. In addition, developments are presented that are capable of adjusting the clearance and the level of rigidity in a fast topic and in a wide range. It follows that it is possible to obtain add-ons for virtually a variety of conditions of use, thereby satisfying any request with just one set.

It is the front suspension that most often "takes the blows of fate" upon itself, being the most loaded unit of the car's undercarriage. That is why the care and timely inspection of its main components, their repair and replacement will be the key to successful driving of the VAZ 2107.

The entire front suspension of the “classic” is more reliable than subsequent front-wheel drive modifications of the VAZ, since a car with rear-wheel drive has fewer parts in the front suspension, its arrangement is more “economical”.

The design of the front suspension has important components, without which the smooth running of the car is impossible.

Let's describe the front suspension device on a VAZ 2107 car:

• double wishbone suspension, there are upper and lower arms that exist independently; the upper one is fixed through the mudguard strut with a long bolt, the lower one is bolted to the suspension cross member, which, in turn, is connected to the front spars.
• silent - blocks, or rubber-metal hinges of quiet running. They are needed to turn the levers. When worn, replacement is required.
• ball joints, or simply “ball” ones - the wheel hub is ultimately installed to them through the steering knuckle system with the trunnion.
• the damping device includes a spring mounted in the cups and a hydraulic type shock absorber mounted inside the spring.
• the list of main devices is completed by a bar (stabilizer) of transverse stability.

The device and the most important parts of the VAZ 2107 suspension:

5 - trunnion of the fist; 9 - ball pin of the upper support; 10 - rotary fist; 13, 36 - upper and lower levers; 17 - reference glass; 18 - shock absorber mounting pads; 21 - upper support cup of the spring; 22 - the axis of the upper arm; 29 - bracket for fastening the cross member to the spar; 30 - cross member of the front suspension; 33 - stabilizer bar; 34 - body spar; 37 - bolts for fastening the axis of the lower arm; 40 - shock absorber;

This is what the pendant looks like from below. All structural elements are clearly visible (levers, spring, shock absorber, stability bar, ball joints, etc.).

What malfunctions can the suspension have?

• Drying out and simple wear from time to time of rubber parts, anthers, liners, seals, deterioration of ball bearings, wear of the cushions of the stability rod;
• "Fatigue" of the metal, in which the breakage of springs and shock absorbers is possible.

The front suspension, unlike the engine, was more fortunate, since it is easier to carry out repairs in a home garage, and the design of the suspension is open. To do this, you need a flyover or an ordinary viewing hole.

What can be determined when inspecting the suspension?

• Condition of wear, crumbling, dryness of all rubber parts;
• It is determined how dry the shock absorber is and whether there is any oil leakage from it, as well as evaluate its performance. The test scheme is simple: you need to sharply press on the surface of the wing of the car and remove the load, that is, “sharply release”. A good shock absorber returns the wing up in one pass, without additional oscillation.
• Integrity of all coils of springs on the right and left sides;
• The clearance in the ball bearings is determined.

Ball joint replacement

The scheme of work (like all others) begins with cleaning parts from dried dirt. It is necessary to make it a rule to clean all the elements at the bottom of the machine, before starting diagnostics and repairs. It is most convenient to do this first with a jet of water from the nozzle of a portable car wash, and then dry with compressed air.

To replace the ball bearings, first remove the wheels of the VAZ 2107.

Jacks for loading the lower part of the suspension rest against the lower arm, simulating the "load" on the suspension.

• Unscrew the ball pin nut (for example, the top one).
• With a special press tool, the steering knuckle and the support pin are separated;
• Turn out the ball joint and remove it in a protective case.
• A new support is put in, and the assembly takes place in the reverse order.

The lower support is also being replaced. After that, the car is jacked up on the other side and the ball joints on the other side of the suspension are replaced.

After that, it is necessary to adjust the wheel alignment, this must be done at a service station on a special stand.

Silent blocks.

Recall that the silent block is a connecting element in the suspension of the VAZ 2107, and indeed of any other “classic”, which has an elastic liner made of polyurethane or rubber in order to soften the shocks of the suspension and vibrations. These parts take on large shock loads.

The figure shows the mounting diagram of the silent block of the lower arm.

Because of this, silent blocks are capable of wear, as a result of which the collapse - convergence is upset. It is advisable to change silent blocks every 50-100 thousand km. Run.

Replacing shock absorbers

The shock absorber is a non-separable paired part. That is, if one of them fails, then both change.

In order to replace the shock absorber, you need to carry out the following steps:

• We unscrew the fastening nut on the rod;
• We remove the washers along with the top cushion made of rubber;
• We unscrew the bracket with which the shock absorber is connected to the lower arm;
• A broken shock absorber can be removed through a slot in the lever body;
• The bracket is removed from the shock absorber and a new shock absorber is installed in the reverse order.

Replacing a broken spring

To replace the spring (which is also beyond repair), you need to remove the shock absorber, disconnect it from the anti-roll bar. After that, you need to loosen the screws of the lower arm, after that it is jacked up, then using a special puller we remove the ball pin.

The front suspension of the VAZ 2107, as the most loaded element, takes on most of the mechanical load when driving. Therefore, the owners of the "seven" pay special attention to it both during repair and when tuning a car.

Suspension device VAZ 2107

"Seven", like its predecessors, has a double wishbone suspension with independent levers. The upper levers are attached to the mudguard strut, the lower ones - to the cross member holding the front spars.

For free rotation of the levers on the axle, silent blocks (rubber-metal bushings) are used, thanks to which the lever retains mobility, but does not “play” on the axle and does not knock.

The wheel hub is mounted on ball joints, which allow it to freely rotate along the vertical axis.

A smooth ride when driving through bumps is provided by springs and shock absorbers that dampen vibrations.

Possible malfunctions of the VAZ 2107 suspension

Suspension failures can be divided into groups:

• drying and wear of rubber parts: anthers, bushings;
• wear of liners and seals, which is the cause of failure of ball bearings, anti-roll bar cushions, silent blocks;
• metal fatigue leading to breakage of shock absorbers, springs and even levers.

Checking and repairing the front suspension is a fairly simple operation. They are carried out on a viewing hole or a lift.

What can be revealed when inspecting the suspension

During a visual inspection of the suspension, the following problems and malfunctions can be identified:

• condition of rubber parts;
• determination of the state of the shock absorber (signs of oil leakage, performance);
• integrity of springs, levers;
• the presence of play in the ball bearings.

Possibilities of tuning the front suspension VAZ 2107

The design of the VAZ 2107, especially the suspension, is not far from the outdated FIAT 124. Therefore, suspension tuning is so popular - the owners are trying to improve its performance. The goals for which tuning the front suspension of the VAZ 2107 is carried out are as follows:

• increase in smoothness of the course;
• improved manageability;
• increased stability at high speeds;
• increasing the reliability and durability of components and parts.

One of the simple and effective ways is to install high-quality components from foreign manufacturers. This is especially true of shock absorbers, a wide selection of which allows you to solve many problems and customize the "seven" for yourself, making its move either softer and smoother, or harder, but stable at high speed.

Below we consider the most popular types of tuning.

Installing a sports suspension

To improve stability and handling at high speed, the following changes can be made to the suspension:

"Castor" - the angle of the longitudinal inclination of the axis along which the wheel turns. This is the angle, measured in the longitudinal plane, between the vertical and the line of the center of rotation of the wheel. A larger castor provides better handling due to more eversion of the wheels. But at the same time, turning the steering wheel is difficult.

The castor is increased by installing offset upper supports or wishbones.

Gain Stabilizer

One of the tuning options that allows you to strengthen the structure and improve the car's handling on a bad road is the installation of a double stabilizer. This modification is often made when creating a "sports" suspension of the VAZ 2107. This requires a little: a new anti-roll bar and rubber bushings of the stabilizer.

To carry out tuning of the front suspension of the VAZ 2107, you will need a welding machine. The dual stabilizer is installed as follows:

1. remove the rubber bands from the bushings, weld the metal rings of the bushings in pairs (welding a pair to the stabilizer mounts to the spar) and put the rubber bands in place;
2. cut the edges of the new stabilizer by 7-8 cm and remove the attachments to the side member;
3. connect the stabilizers by inserting them into the modified pillows and mounts;
4. screw the structure to the car.

Such tuning of the VAZ 2107 suspension reduces roll when cornering, improves the car's response to steering and “working out” road irregularities.

Improvement of the suspension arms

The studs of the lower arm are subject to corrosion and therefore often break, and this often happens already during assembly - when tightening the nuts. To prevent corrosion, do the following:

• before tightening the nuts, lubricate the studs with lithol or grease;
• install plastic caps on the protruding part of the thread of the studs.

Caps can be made by melting plastic tubes of a suitable diameter or using caps from a ballpoint pen.

After such refinement, the stud will be protected from corrosion and will not be damaged when the nut has to be removed and installed next time.

If the studs are already broken, you can cut off the rest of the stud, make a hole and either insert a bolt and nut into it, or cut the thread and screw in the bolt. The last option is optimal - the final design almost completely corresponds to the factory one.

Strengthening the anti-roll bar mounting brackets

The stabilizer brackets, with which it is attached to the spars, are made of fairly thin metal. The loads on the brackets during active driving on bad roads are so high that it can cause deformation and cracks. To avoid this, you can carry out a simple tuning of the VAZ 2107 suspension - they reinforce the attachment points.

To strengthen the brackets, steel corners with a thickness of 2-2.5 mm should be welded. After welding, reinforced brackets should be cleaned and painted or coated with an anti-corrosion coating. When installing reinforced brackets, the stabilizer rubber bands should be changed.

VAZ 2107 in the original looks quite modest. The same modest are the dynamic characteristics of the car. Therefore, many car owners refine and improve almost all components and systems of the car: the appearance changes, the interior becomes more comfortable, engine power increases, etc.

Radical tuning VAZ 2107

You can turn a serial sedan that rolled off the assembly line at the beginning of the 21st century into a car that vaguely resembles the original using tuning. Examples of professional tuning can be seen at various international competitions, for participation in which cars are specially modified and finalized.

Concept of tuning

The term tuning literally translates from English as tuning or adjustment. Any car can be tuned to such an extent that it becomes unrecognizable. Each owner refines his VAZ 2107 in his own way, individually determining which components and parts need to be modified.

Before starting tuning both the car as a whole and any component, it is important to understand a number of simple requirements. Modernization of the car should not contradict Russian legislation and traffic rules (SDA). First of all, this concerns external tuning of the body, replacement of wheels and disks, external and internal lighting. Everything that is attached to the sides and front of the machine must not: have parts protruding beyond the dimensions, be poorly welded or screwed, contradict the requirements of UN Regulation No. 26.

There are three types of tuning.

1. Technical tuning: improvement of engine performance, refinement of gearbox, transmission, running gear. Sometimes this task is solved radically - standard units and mechanisms are changed to units and mechanisms from other car brands.
2. Interior tuning: making changes to the interior of the cabin. The design of the front panel, seats, ceiling is changing, which are sheathed with fashionable material, inserts are made of metal, expensive wood, etc.
3. External tuning: completion of the body. Airbrushing is applied to the body, body kits are installed, the configuration of thresholds, fender liner, etc. is changed.

An example of tuning VAZ 2107

The appearance of the VAZ 2107, shown in the figure, has changed a lot due to an unusual home-made front bumper, crate, front fenders and sills painted green.

Ground clearance decreased from the factory 17 cm to 8–10 cm, which gave the car a similarity to a racing sports car and had a positive effect on stability and handling. Painting made the car noticeable in the traffic flow. Thus, external tuning made the ride safer and gave the VAZ 2107 a memorable appearance.

Body tuning VAZ 2107

VAZ 2107 is ideal for external tuning for the following reasons.

1. The car initially has a discreet appearance.
2. On sale there is a wide selection of parts, accessories, accessories for tuning at affordable prices.
3. The car does not have complex electronics, automation, self-diagnosis systems that could be damaged during work.

Most often, external tuning is limited to window tinting and the installation of stylish rims. To give the VAZ 2107 body a streamlined shape is a practically unrealizable task. However, for the speed characteristics of the car, this is not necessary. It is possible to reduce the force of air flow under the bottom due to the installation of low-lowered spoilers, which harmoniously integrate with the base of the body at the places where the thresholds and bumpers are installed.

You can give the car body a sporty look due to:

Body kits and bumpers are made independently. It is very important to properly cut and bend them. To do this, you can use special computer programs.

Windshield tinting

In accordance with the traffic rules, it is recommended to tint the windshield only at the top with a strip width of no more than 14 cm. This will protect the driver's eyes from the sun's rays. To tint you will need:

• tint film 3 m long and 0.5 m wide;
• glass cleaner or shampoo;
• rubber scraper to remove water;
• napkins made of non-woven material;
• marker;
• sharp thin knife (can be clerical);
• roulette;
• spray bottle.

The tinting process itself is carried out as follows.

1. The windshield is removed from the body and freed from the sealing gum.
2. The glass is transferred to a bright, clean corner of the room, where there is no dust.
3. Glass on both sides is thoroughly washed with soapy water. Strong pollution is removed by means of solvent.
4. The tint film is applied to the outer side of the glass and outlined with a marker with a tolerance of 5–7 mm.
5. On the applied line, the film is cut with a sharp knife.
6. The protective layer is removed from the film.
7. The surfaces of the glass and the adhesive side of the film are wetted with soapy water.
8. The film is applied to a clean, damp surface. In this case, the formation of horizontal folds should not be allowed.
9. The film is gently pressed with a plastic or rubber scraper from the center of the strip to the edges. At the same time, wrinkles are smoothed out. It is advisable to warm the film with a building hair dryer. There should be no bubbles between the film and glass. If they appear, they should be driven out with a scraper to the side that has not yet been glued, or pierced with a thin needle.
10. The glass dries for several hours and is installed on the car.

headlight tuning

The easiest and most affordable way to tune the headlights and taillights of the VAZ 2107 is to replace standard light bulbs with LED ones.

To do this, they usually use a special tape with spotlights glued to it. In this way, you can make original running lights, angel eyes, etc. You can also purchase already tuned front and fog lights and taillights in car dealerships.

Tinted rear window and installation of a decorative grille

If the car owner does not have tinting experience, it is advisable to purchase the cheapest film for darkening. There are no restrictions on light transmission for the rear window. Tinting is carried out without dismantling the glass, as it is glued to the sealing gum. The work will require the same materials and tools as for the windshield. The film is glued from the inside in the following order.

1. The glass is washed with soapy water, and heavy dirt is removed with a solvent.
2. The tint film is applied to the outer wet side of the glass.
3. Toning is given the shape of glass. To do this, the film is pressed against the glass and smoothed out under a stream of warm air from a building hair dryer. In order not to overheat the tinting, the air temperature should not be too high. The hair dryer moves along the entire surface of the film, stopping at each place for 2-3 seconds.
4. The protective layer is removed from the tint film, and it is glued from the passenger compartment to the wet inner side of the glass. Since the film has taken the form of glass, it should fit snugly enough. Water from under the tinting is expelled with a scraper.

Sometimes, instead of tinting, a decorative grille made of two-millimeter plastic is installed on the rear window, which can be purchased at a car dealership. For ease of installation, it consists of two halves and is easily attached to the rubber seal of the rear window from the outside. The grille can be painted to match the color of the car or left as is.

Roll cage installation

Installing a safety cage will help protect the driver and passengers of the VAZ 2107 in extreme situations. The work on the installation of the frame is quite complicated. In order not to disturb the geometry of the body, careful sizing, welding and fitting pipes in the cabin using hand-held power tools will be required.

Tuning salon VAZ 2107

The original looks very modest. The lack of frills provides the car owner with ample opportunities for tuning. Before radical interior tuning, seats are removed from the cabin, doors are dismantled and disassembled, the steering wheel, dashboard and rear panels are removed, as well as trim from the floor and ceiling.

Noise insulation of the VAZ 2107 cabin

Internal tuning should begin with the installation of a new sound insulation, without which it makes no sense to install a high-quality audio system. During the installation process, preliminary preparation for tuning of all interior elements is carried out. Depending on the readiness of the body surfaces, the insulation can be installed either in parts or completely. First, the outer wheel arches and the bottom of the car are processed, then the trunk, hood, floor and ceiling of the passenger compartment, doors and instrument panel. After dismantling the engine, the partition in the engine compartment is isolated.

Necessary tools and materials

For soundproofing you will need:

• set of open-end wrenches;
• set of spanners;
• set of heads with extension and ratchet;
• building hair dryer;
• a set of screwdrivers with different blade shapes;
• vibration-insulating material on a mastic basis ("Vibroplast Gold" or "Silver") with a thickness of 4 or 8 mm;
• Shumka (products of the Shumoff and StandardPlast enterprises).

floor soundproofing

Floor soundproofing is carried out as follows:

1. The fasteners are unscrewed and the front and rear seats are removed.
2. The factory coating is removed from the floor.
3. The floor is degreased and treated with a special mastic.
4. The floor is covered with soundproofing material.

Experts advise laying thin Shumka in several layers without gaps and gaps. Noise isolation is more effective than when laying thick material in one layer.

Front panel tuning

There are a lot of opportunities for tuning the front panel of the VAZ 2107. You can fit it with expensive material, make inserts from aluminum, chrome or fine wood. For devices, you can make LED lighting or install a GF 608 Gamma panel with an on-board computer. The steering wheel can be replaced with an analogue from a foreign car, covered with leather or other material.

Obviously, before tuning, the dashboard must be dismantled.

Replacement upholstery and seats

You can effectively change the appearance of the cabin by replacing the seat trim, ceiling, front and rear panels, doors with more modern and practical materials. At the same time, it is not recommended to use fleecy materials (phlox, carpet, etc.). When cleaning such surfaces with a vacuum cleaner, their surface will quickly lose its original appearance. To replace the seat upholstery yourself, you will need a sewing machine and the ability to handle it.

On sale there are special inexpensive kits for tuning the VAZ 2107 interior, consisting of plastic decorative overlays on the dashboard, sun visors, armrests, door cards, acoustic grilles, etc. Such a kit can be matched to the color of the car and choose different versions.

Seat upholstery

The ideal option is to install more modern seats in the VAZ 2107 interior. Seats from Toyota Corolla produced in 1993–1998 are ideal, the fastenings of which coincide with the standard seat bolts of the VAZ 2107. However, it is quite expensive.

For seat upholstery you will need:

• material (fabric or leather) for sheathing;
• foam rubber;
• glue "Moment" or equivalent;
• electrical tape or tape;
• sewing machine;
• thick needle;
• threads of a suitable color;
• sharp knife;
• awl;
• set of wrenches;
• hammer;
• Screwdriver Set.

Work is performed in the following order:

1. The front seat is removed from the rails and placed on a flat surface.
2. The old upholstery is torn at the seams. In this case, it is necessary to prevent damage to the edging.
3. Places where the skin is glued to cardboard inserts are wetted with gasoline.
4. The old upholstery is gently pulled off the backrest and seat cushion.
5. A pattern is made from the new material along the contour of the old skin with scissors.
6. On a sewing machine, the trim parts and edging are sewn with a double seam. Depending on the material, the joints can be stitched by hand, glued or heat-welded.
7. The foam rubber and sagging seat springs are being replaced.
8. The new upholstery is carefully stretched over the back and cushion of the front seat.

The rear seat also folds in the same way.

Replacement door cards

Installing new door cards will also noticeably refresh the interior of the VAZ 2107. This is quite simple to do. As new cards, you can use plastic overlays under the tree. Alternatively, you can buy a set of various inserts for the VAZ 2107 interior in the store.

Interior ceiling trim

Some car owners attach hardboard to the ceiling of the VAZ 2107 cabin and already glue carpet on it. It is quite long and laborious, but the result is very effective. Before starting work, the windshield and rear windows are dismantled.

Sometimes the standard upholstery is changed to leather or some other material. However, before this, the sound insulation of the ceiling should be strengthened. For this:

• the factory noise is carefully removed;
• the metal surface of the ceiling is degreased;
• a vibration damper is glued to the degreased surface (experts recommend using a building hair dryer);
• a layer of splen is glued on the vibration damper;
• the surface is covered with factory noise.

Other possibilities of internal tuning VAZ 2107

Tuning salon VAZ 2107 can be supplemented:

• replacement or modification of sun visors and rear-view mirrors;
• changing the interior lighting with the installation of lamps for the legs;
• installation of a new radio and acoustic system;
• installation of electric windows;
• replacement of standard rugs with decorative ones;
• modernization of other parts, devices and devices.

Tuning engine VAZ 2107

The manufacturer installed on the VAZ 2107:

• carburetor engines with a volume of 1.2 and 1.3 liters;
• injection engines with a volume of 1.5 and 1.6 liters.

The most common types of tuning power units are:

• increase in the working volume of combustion chambers;
• camshaft replacement;
• installation of an air filter of zero resistance;
• conversion of the exhaust system to a straight-through muffler.

The installation of a turbo kit on the engine gives the greatest effect.

Ways to increase the power of the VAZ 2107 engine

You can increase the power of the VAZ 2107 engine in the following ways.

1. Tuning of a head of the block of cylinders. Due to this, you can increase the power by 15-20 liters. With. Since the head is made of cast iron, all operations for its completion are quite difficult and time consuming.
2. Carburetor tuning. The diameters of air and fuel jets are changed, enlarged diffusers are installed.
3. Installation of two or four carburetors.
4. Installation of a turbocharger, consisting of a compressor and a turbine.
5. Boring cylinders to increase their diameter.
6. Installation of forged lightweight pistons instead of cast ones.
7. Replacing the standard air filter with a filter of zero resistance.

On injection models VAZ 2107, it is recommended to carry out software chip tuning. This will not only optimize the performance of the engine, but also normalize the operation of the electronic control unit. The effect will be maximum if chip tuning is performed on a serviceable engine that has passed a full technical inspection.

Tuning the exhaust system VAZ 2107

Some car owners make the engine sound louder to make it sound like the growl of a sports car. To do this, the catalyst is replaced with a special flame arrester. Other owners of the VAZ 2107 believe that tuning the exhaust system is justified if the result is an increase in engine power. When evaluating the feasibility of such measures, it should be borne in mind that improper installation will lead to an increase in fuel consumption and a deterioration in vehicle performance. Therefore, work on tuning the exhaust system should be entrusted to professionals.

When tuning the exhaust system, do not forget that the maximum sound level of the engine should not be louder than 96 dB. Alteration of exhaust gas removal devices cannot worsen the environmental class of the engine.

Tuning the exhaust manifold and downpipe

For better exhaust gas purge, extreme people change the standard exhaust manifold to a StinGer spider complete with a double stainless steel intake pipe (pants). This allows you to increase power at high speeds by about 9 hp. With. At the same time, the formula for the output of exhaust gases "4-2-1" does not change.

Since the internal walls of the StinGer are smoother, the installation of such a collector will increase the efficiency of the exhaust gases and increase the power at maximum speed by 9 hp. With

The flat surfaces of the StinGer manifold flanges ensure a snug fit to the cylinder head and to the pants. However, the new downpipe does not have a threaded seat for the oxygen sensor. Therefore, if necessary, a nut is welded on this pipe in front of the catalyst, into which the sensor is installed.

Since the pants end with a flange, the resonator of the injection model is connected without problems. However, on the carburetor VAZ 2107, this assembly is made differently, so it is better to immediately install a resonator from the injection engine on such a car.

Installing a straight-through muffler

The standard VAZ 2107 muffler consists of two pipes welded at different angles and lined with non-combustible mineral wool filler, which reduces the exhaust gas velocity and softens the exhaust. To increase the volume of the exhaust and make the flow of exhaust gases straight, an audio tuning of the exhaust system is carried out. Instead of a conventional muffler, a do-it-yourself straight-through is installed.

In a straight-through muffler, the exhaust gases do not make turns that dampen speed, and are additional resistance that reduces engine power.

Thus, with the help of tuning, you can turn the VAZ 2107 into a completely new car. In accordance with the wishes of the car owner, almost any components and parts are being finalized, including the engine. Elements for tuning are commercially available, and most of the work, carefully following the instructions of professionals, is quite simple.

“Seven” is the last rear-wheel drive car in the VAZ model range. The front suspension of the VAZ 2107 has fewer parts than the “older” front-wheel drive models, so repairing it is easier.

Front suspension device VAZ 2107

The "Seven" is equipped with an independent suspension, consisting of an upper and lower arm, a spring and a shock absorber on each side. The lower arms are interconnected through the anti-roll bar.

The axes of the lower arms are rigidly attached to the cross member (beam), which is fixed to the front spars of the body. The role of the axes of the upper levers is performed by the mounting bolts, with which the levers are bolted to the racks of the mudguards.

The mobility of the levers is provided by rubber-metal hinges - silent blocks.

The wheel hub is bolted to the steering knuckle, which is held at the ends of the levers by ball bearings (upper and lower). This ensures that the wheels turn around a vertical axis.

The front suspension springs, which smooth out bumps when driving over rough sections of the road, are located between the lower control arms and the mudguard. That the springs did not move during the ride, their edges are inserted into the support cups.

Shock absorbers that absorb vibration energy are attached to the body of the lower arm, and their rods are screwed to the mudguards through rubber pads.

The anti-roll bar is connected to the arms and spars through rubber bushings to eliminate direct metal contact and compensate for shock loads.

Malfunctions of the front suspension VAZ 2107

Repair or replacement of the VAZ 2107 front suspension is required in case of wear or breakage of its parts. Rubber and rubber-metal bushings, shock absorbers and ball bearings are most subject to wear. The breakdown of the latter is the most dangerous, since the steering knuckle in such cases turns out along with the wheel, and the car loses control.

To determine the breakdowns, it is necessary to inspect and diagnose the condition of the front suspension.

The inspection consists in checking the absence of oil leaks from the shock absorbers, the condition of the rubber parts of the parts and the integrity of the spring.

Checking the details of the front suspension VAZ 2107

It is easy to check the condition of the shock absorbers: press hard on the wing, forcing the spring and shock absorber to compress and release. The machine should return to its original state and not continue to sway.

The condition of the ball bearings can be assessed by checking the play of parts with a loaded and unloaded suspension.

All rubber parts (anthers, bushings, silent blocks) must be changed at the first sign of wear or damage. Silent blocks must also be replaced if there is play on the lever on the axle.

Replacement of ball bearings VAZ 2107

To replace the ball joint, you need to jack up and remove the wheel. Then unscrew the nut holding the support pin in the steering knuckle and press out the latter.

After that, you can unscrew the support from the lever and remove it together with the anther. It remains to install a new ball joint with a new anther and assemble by performing the previous operations in reverse order.

After replacing the ball joint, it is desirable to adjust the angles of the front wheels (alignment).

Replacement of silent blocks VAZ 2107

Repair of the front suspension of the VAZ 2107 often requires the replacement of silent blocks. To carry out this operation, it is necessary to remove the upper arm. Lower control arm bushings can be changed without dismantling the control arm from the vehicle.

Silent blocks are pressed out of the lever and pressed into it using a special puller. To remove the upper arm, it is necessary to press out the support pin.

The silent blocks of the lower arms can be replaced by unscrewing the nuts on the arm axle. It is worth removing the lower levers only for replacement with new ones. But such an operation is usually required only when eliminating the consequences of an accident.

Replacing the front shock absorbers VAZ 2107

The front shock absorbers of the VAZ 2107 cannot be repaired, therefore, in case of poor performance or the presence of oil leaks, they are replaced with new ones. To replace them, just unscrew the two fastening nuts on the lower arm and the nut that secures the shock absorber rod in the mudguard cup. The shock absorbers are removed and inserted through a hole in the lower arm. To get or insert the shock absorber, it must be compressed.

Replacing the front springs VAZ 2107

The front suspension springs are replaced after the shock absorbers are removed and the anti-roll bar is undocked (the latter prevents the levers from moving freely). Also, to replace the spring, loosen the nuts securing the lower arm axle.

To lower the lower arm as much as possible and release the spring, it is necessary to press the lower ball joint pin out of the steering knuckle.

A new spring must be compressed and fixed with special ties before installation.

The assembly of the node is carried out in the reverse order. Couplings from the spring can be removed only after attaching the ball pin in the steering knuckle.
