Body weight of VAZ 2107: reducing the weight of the car with your own hands

Car body

The body of the VAZ 2107 car is a rear-wheel drive four-door sedan. The assembly diagram of its frame is standard and has the following elements:

• Front parts;
• Front fenders with reinforcements;
• Roofs with glass frames;
• Reinforced floor and rear panel;
• Side parts;
• Hind wings.

Each element is cast from mild steel. Each part has not only its own number, casting pattern, but also its own thickness. For example, for the roof it is 0.9 mm, and for the rear wheel arches - 1.0 mm.

Most parts are connected using non-contact welding, but parts that bear a large load are additionally strengthened by arc welding.

Among the mounted parts it is worth highlighting:

Dimensions and specifications

Regardless of the configuration, the VAZ 2107 has the following dimensions:

- curb weight (how much is the weight of the car with equipment and materials) - 1030 kg,

- total weight (how much does a loaded car weigh with passengers and cargo) - 1430 kg

A motorist needs to know not only the standard parameters of his car, but also the control dimensions.

Control dimensions (points) are usually necessary when restoring a car after an accident. If you buy a used car, knowing these control dimensions, you can easily find out whether the car has been in an accident. This geometry will help in restoring the body, as well as other important parts.

The main control dimensions are described in detail in the diagram below:

The linear dimensions are clearly defined by the following diagram:

Dimensions of trunks VAZ 2107

The width of VAZ 2107 luggage racks for all modifications is 350 liters.

Rack parameters for standard modifications:

Years of production 1982 - 2012:

• Height: 610 mm;
• Diagonal: 1496 mm;
• Diagonal: 1496 mm;
• Volume (years of production 1985 - 1995): 350 l.

Checkpoints:

All luggage rack measurements are given based on control points, which are different for different cars, and in general have the following meaning:

• A: top left corner;
• B: top right corner;
• E: inseam to the far left (bottom corner);
• D: Inseam to the far right (bottom corner).

Important: in the case where the car does not have control points, the data is presented in the format length - width - height.

Identification data

The VAZ 2107 car, like any other car, has specific passport data, the liver of which is indicated in the table located under the hood on the air box.

The plate contains information about the vehicle model, engine number and body number, weight data and spare parts number. Above it is the vehicle identification number - VIN.

— The first 3 letters are responsible for the manufacturer’s code;

— 6 subsequent digits are the decoding of the car model;

— A letter or number of the Latin alphabet indicates the year of manufacture of the VAZ 2107 model;

— The last 7 digits are the required body number.

You will find the exact same number in the trunk.

Famous pickup truck

For those who were looking for a spacious, convenient option, a pickup truck in any color was produced based on the VAZ 2107. It is called the VIS-2345 pickup, but it is also no longer produced. But despite this, it is still popular.

This subcompact pickup truck is easy to drive, giving you plenty of flexibility to haul as much stuff as you need. Even a refrigerator will fit into the wide isothermal booth.

The two-seater pickup truck has a fuel-injected engine. It reaches speeds of up to 110 km/h. Due to its convenience and original design, this body type is very common in America and Europe - so it’s a shame that production of this model was stopped.

Body replacement

The VAZ 2107 sedan or pickup truck has not been produced for several years, but drivers can still purchase bodies for their cars if necessary. If you suddenly get into an accident, or the body of your car is in disrepair, you can easily order a new one.

The action plan is simple. First, you will need to decide on the necessary equipment, as well as what type of body you need.

One package includes a new “body assembly”, which includes electrical appliances, wiring, glass, front and rear bumpers;

The other configuration is called “body in metal”. It includes a new body painted in the desired color and treated with anti-corrosion agents.

The factory provided various colors for the VAZ 2107. Each of them has its own name. For example, pale yellow is “melon”, classic red is “viburnum”, and marsh green is “Sochi”.

When ordering a body in the third configuration, you can make it in any color. It may take longer than if you had stuck with plain white paint. But a car with a bright, noticeable color will always be fun to drive.

The style of the classic AvtoVAZ 2107 model is quite elegant and strict. “Seven” is a symbol of an entire era, when, after the fifth and almost identical sixth model, car enthusiasts experienced a long-awaited update of the series. As a tuning item, the car is in great demand. This applies to the technical interior as well as the exterior. Selecting a roof rack for the VAZ 2107 is no exception.

Dimensions of VAZ 2107 length and width

VAZ 2107 is a five-seater passenger car of a classic layout with a front longitudinal arrangement of the power unit and rear drive wheels. The engine is a four-cylinder, four-stroke, eight-valve, in-line, carburetor or fuel injection system. The body is a supporting structure, all-metal, welded. Body type - sedan .

Overall dimensions of VAZ 2107

The VAZ 2107 car is equipped with a carburetor engine of the VAZ 2103 model with a working volume of 1.5 liters. The modification of the VAZ 21074 car is distinguished by the engine of the VAZ 2106 model with a displacement of 1.6 liters.

In recent years of production of this model, modifications of the VAZ 2107-20 car with a VAZ 2104 engine with a displacement of 1.5 liters and VAZ 21074-20 with a VAZ 21067 engine with a displacement of 1.6 liters, equipped with fuel injection, mechanical part (cylinder block, connecting rod) were produced -piston group, crankshaft) of these engines are respectively identical to the VAZ 2103 and VAZ 2106 engines. The VAZ 2104 and VAZ 21067 engines are equipped with more powerful generators and starters with planetary gearboxes. The installation of engines with distributed fuel injection in cars, as well as the use of a gasoline vapor recovery system and catalytic converters in exhaust systems, made it possible to reduce the toxicity of exhaust gases and fuel consumption, and increase the reliability of engine starting in cold weather. The body, chassis and transmission remained unchanged.

The predecessor is the VAZ 2105, the successor is the Lada Granta.

Features of cargo transportation on a VAZ 2107

On the farm, the picture is a little different, since in addition to well-deserved love, the machine accepts and performs hard work:

• Tows trailers. But if we take into account that the plant does not equip cars with a tow bar, then each driver buys or designs a tow bar according to the weight of the payload. In cases where the traction load of the frame is not taken into account, the car suffers.
• Carries building materials sticking out of the windows. But this is not the best option, since the load blocks the visibility area in the side mirrors.
• Carries things in the internal trunk. This compartment on the “seven” requires special consideration. As in all Zhiguli cars, the skin fits the technical components: the gas tank, wheel arches, rear suspension cups and side members, creating a labyrinth. Rational use of the trunk is sometimes difficult.
• Transports long and oversized cargo. For such transportation, only the VAZ 2107 roof rack is suitable.

Stylish tuning VAZ-2107 from Poland

European tuners, especially from the countries of the former USSR, also sometimes get nostalgic by tuning inexpensive Soviet cars. But how cool they do it! Look at this brutal, borderline military-style tuning of our “Seven” and tell us to our faces that you wouldn’t give a lot to ride it.

The project immediately captivates with its appearance due to the combination of a matte military olive body color with deep black wheel rims and a VFTS body kit.

And the use of a V8 engine, an ascetic-sporty interior with a safety cage, a huge hydraulic handbrake handle, a sports steering wheel, and a lowered suspension speaks about the drift orientation of the tuning of this VAZ-2107. Fortunately, this is a rear-wheel drive car. It turned out to be a real “combat classic”.

Types of roof racks for VAZ 2107

The VAZ-2107 car is equipped with drains. This is the original roof design. Moreover, plastic cambrics, which are called moldings, are installed from the factory. Among the well-known designs of luggage racks, the following are common:

• Railings.
• Universal racks.
• Supports installed in standard holes behind the doorway seal.

Option 2107 is a trunk with a rack attached to the gutters. Their convenience is similar to roof rails in that the gutters are quite long, and when using two crossbars on four pairwise connected support posts, the possibility of spatial movement of pressure points opens up. This is a major advantage when transporting cargo of varying lengths. A cargo basket with static supports has less travel. But when it comes to transporting boards over 3 meters in length, the distance on the gutters of 20–35 cm for moving the basket and, accordingly, the center of gravity plays a big role. By the way, it can be added that a length of 4.5 meters or more, protruding behind the bumper at the front and rear, is marked as oversized cargo using a red reflector and a flag. The sign is installed at the rear end of the load, since the front end is adjusted by the driver himself. For optimal operation of the VAZ 2107 roof rack, you will need knowledge about the permissible load and carrying capacity:

• Roof VAZ-2107 – 60 kg.
• Luggage equipment – ​​50–150 kg.

An asymmetrical layout results. But since the value on the roof is fixed, you need to build on it. On a perfectly flat road in the absence of strong side and head winds, as well as proper weight distribution, it is allowed to load the trunk by 75 and even 85 kg. But if you forget about the load-bearing capacity of the roof and prioritize the weight values ​​of an expensive trunk, which are much higher, then deformation of the body support pillars is inevitable. As a result, the doors are not closed properly.

Tuning the suspension of the VAZ 2107

The main goal of tuning the front and rear suspensions is to increase their rigidity.

Rear suspension tuning

To increase the rigidity of the rear suspension, springs, rubber bumpers, silent blocks, and shock absorbers are changed.

Particular attention is paid to springs. When increasing rigidity and power, they should retain the outer diameter of the original

Springs from the VAZ 2121 or VAZ 2102 meet these requirements (they are two turns longer, so they need to be shortened). You can select and install springs from foreign cars, but it will be quite expensive.

When tuning the rear suspension, shock absorbers, springs, silent blocks are changed, and for sports competitions, additional stabilizers are installed to increase the car's stability when cornering.

Selecting new shock absorbers is not difficult, but they must also meet the required characteristics. Sometimes, to give the car stability when cornering, additional stabilizers are installed on the rear suspension.

Front suspension tuning

Most often, in the process of tuning the front suspension on the VAZ 2107, gas-oil shock absorbers are installed. They have greater rigidity and reliability than conventional oil ones, and have an increased service life. Also a good option for tuning the suspension are shock absorbers with a fixed rod, which are stiffer than their counterparts with a fixed body. Silent blocks are usually replaced with polyurethane ones, designed for increased loads. And finally, the bump stops should also be replaced with more reliable and powerful ones.

To increase vehicle stability when cornering, an additional stabilizer is installed

Luggage rack manufacturers

Gutter racks have been produced since USSR times. But due to the bowl-shaped shape and the small number of points of contact with the load, Soviet designs have sunk into oblivion. Although they can be found today as a rarity or an “unkillable” platform for transporting agricultural products.

A typical representative of that era is the BelAZ gutter rack, which is still produced in Belarus to this day. Options for four and six supports differ slightly in load capacity. The total figure is 50 kg. Dimensions 1.3x1.05x0.21 m. Cost 1,200 and 2,500 rubles depending on the number of supports. Consists of 4 single and 4 paired black metal tubes. They occupy transverse positions. Perforated silver plates are screwed to the ends as side edges. The trunk's potential is limited by design.

Currently, luggage devices are made of lightweight, durable alloys using an anti-corrosion coating.

• from Rostov-on-Don is popular for its universal designs, but does not shy away from mounting on gutters. The basic model consists of six parts:
• Paw. Part of the support from the roof side.
• Clamp. Second part of the support.
• Pipe crossbar. It is made of square steel profile.
• Plastic plug. Before threading the crossbar into the rack, the plug is removed from the crossbar.
• Wing with nut. Main fastener.
• Rubber backing. She puts it on her paw.

Load capacity 70 kg. Price from 450 to 900 rubles depending on the length of the crossbars. An excellent budget option, but at speed it shows poor aerodynamics - it is noisy.

The Ant trunk is no different in appearance from the previous one. But the price of 1,750 rubles is explained by a 2-year warranty.

Luggage baskets are installed on the Semerka. They create the necessary volume for small-sized personal items. But boxes on 2107 are a rare phenomenon. If only this is a car that has undergone exterior tuning. Then the shape of the airbox is combined with the curves of the car.

Video about installing a roof rack on gutters

At the end, two main rules should be added for installing luggage accessories on the drains of a VAZ-2107:

1. Maintain alignment from the windshield and rear window.
2. Tighten bolted connections evenly.

And also take care of the roof and operate the trunk in accordance with the instructions.

Body parts of the VAZ 2107 are of welded and hinged type. The first ones are connected using welding points and additionally reinforced with an arc. Attachment parts can be connected using bolts. On the VAZ 2107, body parts conventionally belong to three zones of the car: the front, middle and rear. Let's find out what their purpose is, how they affect the geometry of the body, its aerodynamics and whether they can be modernized.

Adjustment and repair of skewed body parts

First, the body is diagnosed for compliance with general requirements:

• The mounting points of the engine, suspension and gearbox are inspected. Base points - that's what they are called. If they are in order, or in other words, their location meets factory standards, the car's handling and stability will be good;

All dimensions of the VAZ 2107 body geometry

• Next, attention should be transferred to the frame, consisting of individual components. It is to it (the frame) that parts called tails are attached.

A correctly aligned body is one in which all factory dimensions and shapes have been restored perfectly. In other words, the integrity of the body geometry is checked, diagnosed as follows:

• The clearance parameters of the frame and attached parts are checked;
• The design of window openings is checked for compliance;
• The relative position of the factory points on the base is checked.

General view

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

The exterior of the “Seven” generally copies other VAZ models, called “classics”. On the other hand, some parts and components of the frame are not the same. They simply will not fit the general exterior due to the fact that they differ in basic parameters.

Let's start with the front. This area of ​​the car includes these components: the hood, the apron with the front bumper (they are considered more decorative elements) and the fenders.

As for the middle part of the car, this includes the roof of the VAZ 2107, sills, and doors.

Finally, the rear of the car includes the fenders, boot lid and rear apron.

Distinctive features of the “Seven” body

The body of the “seven” has a lot of advantages over the frame structure of cars. First of all, this has to do with reduced weight by 40-45 percent and lower production costs. The assembly itself also does not involve any particular difficulties: a cold-rolled steel sheet is used, usually 08KP, with the ability to draw and good weldability, as well as paintability.

Distinctive features of the VAZ 2107 body

The parts that are most susceptible to corrosion (underbody and its elements) are made from a special sheet of steel. Thus, in the VAZ 2107 of the last years of production, the number of galvanized parts exceeds in weight more than half of the entire body.

The most expensive part of any car is the body. Its production alone requires about half a ton of sheet metal (not cheap) and many other expensive materials.

As a result, the body has special requirements that it must meet:

• Have visibility in accordance with modern standards;
• Have a shape that is optimal in terms of aerodynamics and functionality;
• Seats must be securely fastened;
• Changes to the front and rear parts of the body should be within normal limits in case of unexpected accidents;
• The interior, engine and luggage compartments must have sufficient volume for a sedan;
• Compliance with all standards of painting, manufacturing, etc.;
• And finally, good maintainability.

Hood

Part of the body of the “seven”, covering the engine compartment. This is the main purpose of the body element: to protect the “heart” of the car from the influence of the external environment and protect it from prying eyes. The hood also has another purpose, albeit a secondary one:

• The aerodynamics of the car to some extent depend on the hood;
• The hood improves air flow to the engine. The air flows directionally and better through special air intakes and additional type of slots made in the hood;
• The hood is able to absorb the hum and slight shaking that the internal combustion engine produces during operation. This is especially noticeable at high speeds.

The connection to the body of the VAZ 2107 is carried out with hinges and bolts. The hood itself consists of 2 panels connected to each other by edge rolling followed by welding. All seams and joints are carefully sealed with mastic.

Note. The hood on the VAZ 2107 can be adjusted. For this purpose, enlarged holes are provided in the hood hinges.

The price of a hood individually, as a rule, does not exceed 2.5 thousand rubles.

At the factory production stage, the inside of the hood is covered with soundproofing material. As a rule, on the “seven” it is a polymer.

One of the modernization methods: installing a deflector

The hoods of modern cars provide special protection for the windshield and the front of the car. It is called a deflector or simply a “fly swatter”. For the “seven”, the deflector can be purchased separately and installed with your own hands.

The deflector is able to protect the hood well from the adhesion of midges when the car is moving. Because of this, it is popularly called a “fly swatter.” This protection is especially important when driving at high speed.

But this, of course, is not the only function of the deflector. Upgrading the hood in this way can improve the aerodynamic performance of the car and protect the paintwork of the main part from damage. In particular, this applies to the following points:

• The flow of oncoming air after installing the “fly swatter” will go over the windshield, leaving the last element clean. The most important thing is that the wind will no longer interfere with forward movement so much, since most of it will go up;
• The hood itself will be protected from chips and scratches that previously occurred from small stones and grains of sand in the oncoming traffic.

You can easily install the part with your own hands on basic type fasteners, that is, metal plates. The latter, as you know, come with holes and are attached on one side to the deflector, and on the other to ready-made mounts on the hood of the “seven”. See the photo for a standard fastening with a self-tapping screw.

The hood of the VAZ 2107 has the following dimensions in mm: 950x70x1420. It weighs about 14 kg. It has one of the important meanings in the geometry of the entire body, although it is a hinged element.

Facing panel (apron) and front bumper

The facing panel or front apron on the “seven” plays more of a decorative role. But besides giving a stylish appearance, an apron also provides many benefits. In particular, thanks to it, during rain, water does not fly directly onto the windshield, but is cut off by this element.

The apron is located directly under the bumper and is a flexible shield that also serves to prevent damage to the front of the car from splashes from under the wheels.

This structural element of the body has special holes for the front bumper brackets and the radiator grille (the latter is attached to it). The apron, due to its “extreme” location (bottom and front), becomes vulnerable to impacts and corrosion. Connected to the body by spot welding.

The design of the "seven" apron must be thought out carefully and correspond to the shape and geometry of the entire car body, otherwise it will simply vomit at high speed. In addition, non-compliance with geometry and design will lead to increased fuel consumption at high speed.

The price for a front apron for a VAZ 2107 individually starts from 600 rubles. The part may be of different workmanship, have a different color and different design features.

Front aprons, sold as a separate element of body decor, come with special mounts to the bumper. As for the original Semerovo ones, they are welded, as mentioned above, to the car body.

The rear apron is also required and must have special fastening plates that ensure its immovable condition and prevent it from coming off on the road.

Front bumper

The bumper is not only designed to retain the energy of a frontal impact first, but also plays a significant role in the exterior design of the Seven. In other words, this is a beam located in front and protects the body from damage in minor collisions.

Thanks to modern synthetic-based materials, bumpers have become much lighter and more beautiful than they were before. Thus, elegant bumpers with bent edges also serve as spoilers, increasing the downforce of the car.

The front and rear bumpers on the VAZ 2107 are made of plastic or thin metal and have chrome trim. They are mounted using special brackets.

The front bumper is equipped with a platform for attaching a license plate and for this reason is 5 cm wider than the rear one.

Today, the owner of the “Seven” is offered three options for bumpers for the VAZ 2107: plastic, plastic with chrome lining, and with brackets for fastening. The price starts from 600 rubles.

Front bumper tuning

Modernizing the front bumper of the “Seven”, first of all, means improving the appearance. To be honest, the factory bumpers of the VAZ 2107 family look, to put it mildly, fake. They do not carry any visual, or even more importantly, high-quality functionality.

Rostov tuning VAZ-2107 with heavy aero body kit

The author invested quite a lot of money in this project. “A coward doesn’t tune a VAZ”—that’s the motto it was created under. As you can see, it turned out very well, original and impressive. You won’t find another “seven” like this anymore.

The central design element is an exaggeratedly large, toothy radiator grille in one block with a massive front bumper. The new “big-eyed” optics and the “eyebrow” lining above them make the entire appearance of the car humanized, with a serious facial expression. Oddly enough, even with such deep tuning, this car has a fairly high percentage of recognition of the original original.

The car is powered by a 152-horsepower, pumped-up 1.9-liter engine. Lowered suspension with Plaza sport shock absorbers + Klaxon springs, cut to 2.5 turns, front Monro Adventure shock absorbers + springs from Chevy Niva, cut to 2.5 turns. Lucas brake system. Wheels 17 inches, Michelin tires. And much more. Result: 12 cups and two articles in two specialized magazines. A clear success!

Wings

The front fenders on the VAZ 2107 are a separate body element with an arched cutout for the wheel. They are fastened by welding, although on most modern cars the fixation is carried out using plastic or metal fastening elements.

The main task of the wing is to protect against dirt and stones from under the wheels getting into the interior through the open glass when the vehicle is moving. The front wings are located along the engine compartment.

In addition to these functions, the wing plays an important role in the aerodynamics of the vehicle. It is not for nothing that designers working in factories and factories of famous automakers constantly subject this body element to restyling. They try to give the wings the most streamlined shape in order to reduce the rate of counter resistance or CRL.

The rear fender is also attached to the body by welding, just like the front fender. Fixation is carried out to the side of the body, the rear panel and to the floor of the fuel tank (right). To strengthen the wing, amplifiers are standardly installed on the part from the inside. The right wing is equipped with a filler flap for the fuel tank.

Instructions for replacing the front and rear wings on the "seven"

The front wing, due to its location, is often exposed to external influences and is soon damaged. Find out how to replace it yourself. Here's what to do:

• Remove the hood, bumper and other body parts that impede access from the car;
• Identify by eye the spots of spot welding. They are located in the following areas: at the installation site of the headlight, near the engine compartment on the gutter and in the door connection area;
• Take a drill and cut off the welding spots.

Advice. If the drill does not “take” welding, you can use the welding method of tearing off points.

• Using a chisel with a sharp end, disconnect the points connecting the part to the front of the car, the bottom and the pillar;
• Remove the wing;
• Using a grinder or the same chisel, knock off the remaining parts on the body.

The new wing is installed like this: first it is secured with a clamp and welded in spots, temporarily. The clamp is removed, compliance with the gaps is checked, and only then the part is finally welded to the body.

With some differences, the wing is castled from the rear:

• First, the trim in the trunk is removed, in the cabin the rear seats are dismantled;
• The wing is cut off with a grinder. In this case, it is recommended to deviate from the factory seam by 1 cm;
• Use strong pliers to grab the remaining metal on the body and remove it;
• Carefully inspect the arch and, if necessary, repair it, with mandatory primer treatment;
• The new wing is installed like the front one.

After welding work, be sure to grind the seams with a grinder and cover them with materials with high protective properties. It is advisable to coat the inside of the wings with anticorrosive.

The cost of a wing usually starts at 850 rubles.

Professional enhancement

Now about the professional way to strengthen the body. This implies an increase in weld seams. As a rule, on the conveyor, body parts of the “Seven” are connected using point technology. This makes the body weak and not durable enough. From the same spacers, it may not withstand and fall apart.

By welding additional metal-type plates and reinforcements into insufficiently rigid areas of the body, the overall reinforcement can be significantly influenced.

Front end reinforcement

It is advisable to boil the front end first. You can buy a TV consisting of 2 parts and weld them together carefully. Lay the welds, install the front engine support bracket, add a gusset, install strong crabs.

Front reinforcement

It also makes sense to weld the seams of the side members. From the inside, steel linings will have to be installed on the side members to further strengthen them.

You can make a window outside the spar, and then insert a piece of channel and boil it. Or simply cover the entire spar with metal cladding.

Spar reinforcement

Be sure to strengthen the cups. The seams are boiled, a plate is placed on top of the cup, which significantly strengthens the part, preventing it from tearing when driving over bumps. Both front and rear cups are upgraded.

Cup and its reinforcement

The suspension mounting elements are strengthened. The seams of the slopes are boiled and a gusset is added.

Such professional modernization gives the same significant effect as installing a subframe. Only in this case the weight of the car does not increase and ground clearance is not lost. It is more convenient to carry out this work from the pit.

Reinforcement of the rear body

Now about how to strengthen the back

Particular attention here should be paid, of course, to the beam. This is what should be strengthened first.

In principle, the fastening itself does not raise any doubts about its strength, but welding with the body leaves much to be desired.

We do the following:

• We climb into the salon, where we find this same triangle;
• Cut it out by indenting 5 mm inward;
• Drill out the studs;
• We make an additional steel triangle from 2 mm iron;
• We weld it into the body;

Triangle attachment

We make holes in it for the bolts, on which we place the beam.

Now you don't have to worry about secure fastening. The beam sits firmly, is held on by bolts that can be removed if necessary and replaced. The connection with the car floor is significant, the triangle is reinforced.

As you can see, it is not necessary to contact professional services regarding body strengthening, where the price of the work may seriously surprise you. The instructions presented above, video review and photo materials will give a clear understanding of doing the work yourself. Be patient and careful and you will definitely succeed!

Roof

It is part of the metal body - the basis of the body. The task of the roof is not only to protect the interior from above, closing it, but also to absorb impact energy in an emergency. On the VAZ 2107, the roof is reinforced with cross members that act as stiffeners.

The roof of the “seven” is directly related to the overall geometry of the body. After an impact or accident, it is imperative to check whether the roof has “slipped.” To do this, the dimensions of the door diagonals are measured as follows: from the bottom of the rear corner to the top corner of the front. In addition, for things to be more convincing, the diagonal of the roof itself is measured.

The cost of the roof, as a separate element of the body, starts from 3 thousand rubles. Dimensions, mm: 1290x100x1550. Weight – 15.6 kg.

Thresholds

The main purpose of the thresholds is to protect the vulnerable sides of the car body. For this reason, thresholds are often susceptible to damage. In addition, when getting in or out of the car, passengers and the driver periodically come into contact with them, scratching the elements with their shoes. As a result, the paintwork comes off from them, which causes corrosion and rotting.

On the “seven”, the classic replacement or repair of a threshold begins with adjusting the door hinges. If this is not done, then it will not be possible to replace the threshold correctly due to the gap.

After this, the following is done:

• The doors are removable;
• The threshold is cut off (first the outer part, then the amplifier);

• The new amplifier is welded through the holes on it, as in the photo below;

• A new threshold is set.

The price for a set of thresholds for VAZ 2107 starts from 200 rubles. The thickness is usually 2-3 mm.

The remaining body parts of the VAZ 2107, such as doors and trunk lid, also have a significant place in the design of the body and its geometry.

Each of the body elements of the “seven” has its own ID number, casting pattern and thickness. So, for the roof - 0.9 mm, and for the rear wheel arches - 1 mm.

Drawings and dimensions of the false floor in the trunk of a VAZ 2107

Based on its geometry, the niche between the side members begs for a kind of organizer for tools, spare parts and small items, which you can easily assemble with your own hands from chipboard or pressed plywood. The cover of this organizer will be a false floor. The result is two independent compartments - one for hardware, the second for luggage.

The design is quite simple to assemble. For assembly, you will need to cut five blanks (or more, depending on the desired number of niches under the raised floor):

The structure is screwed together using furniture screws; the false floor itself, the size of the cover of the first tier, will be the same as the dimensions and contours of the perimeter of the resulting niche.

It is better to screw the hinges to it not in place, but by fixing the lid with several screws and removing the entire structure from the trunk, in a convenient place, on a workbench, for example. After this, you can sheathe the resulting organizer with any material - from leatherette to carpet. As a result, the trunk is always tidy, the floor is level and clean.
