Stretching for Priora, manufacturers, article number and price

If you are interested in improving the performance of your Lada, tuning it and improving it, it is useful to know about the strut brace. The Priora strut extension is a monolithic metal pipe-shaped part that adds rigidity to the front end of your “swallow”. The stability of the car increases, the precision of cornering becomes better.

Similar stretch marks were invented for sports cars. But the suspension of domestic cars is far from perfect, as is the quality of the country’s roads. Therefore, the issue of installing spacers on ordinary civilian cars is becoming increasingly relevant. The price tag is not that big. Installation at a service station or self-assembly - the choice is yours. Let's look at how to secure the front strut strut on a Priora with your own hands.

Front top and bottom

The upper and lower parts are reinforced at the front. The most popular amplifier is the upper extension of the cups of the front shock absorber elements on the Lada Priora. Firstly, they are easy to install, and secondly, they are clearly visible under the hood; their presence, in the opinion of many, gives the car a sporty look. Such designs are indeed widely used in professional motorsport. But a brace alone doesn't make a car a race car.

The part is attached to the front suspension strut cups from above, which creates a rigid connection between the right and left parts of the body. The cost of these parts is 700-1600 rubles. The original Lada Sport spare part is designated by number 21100-8403770-87. Price about 900 rub.

In the manufacturers' catalog there are amplifiers designated as two- or three-point amplifiers, but they are called four- or six-point amplifiers. They differ in the number of mounting holes:

For two-point ones - 2 on each side, 4 in total.
Three-pointers have 3 each, for a total of 6.

Expensive models are available with six mounting holes on each side:

Adjustable - the length can be changed, providing ease of installation on an old car with broken body geometry.
Non-adjustable - simpler in design, more rigid, but suitable only for machines with the correct distance between glasses.
A special type of strut is a stretching of the front struts for a Priora car, with an additional support attached to the engine (for a Priora with a 16 valve engine). The part allows you to increase the rigidity of the body and the mounting of the power unit. It has a complicated design and a price of 1600–2200 rubles.

The lower brace strengthens the suspension arms. The price of the lower part is 500–1200 rubles. The number of the lower reinforcing element of Lada Sport is 21100-5301265-87. Costs approximately 750 rubles. Many car enthusiasts note that installing a lower brace creates a more noticeable effect than adding reinforcement to the cups.

Front strut brace

Stretch bars for the front pillars can be solid or composite, that is, those that can be adjusted in length. Solid guy wires can only be installed in the car model for which they are designed. The composite spacers have a powerful thread and a lock nut, thanks to which such a device can be installed in a car with almost any body width. The linings on the glasses of the racks can also be different.

There are those that are made by hot stamping, and there are also linings that are made by welding individual elements. The strength of the first type of lining is better, but the strength of the second type of lining is enough to make the body much stiffer.

Most A-pillar braces have only two mounting points, but there are models that have three mounting points. The third point is made in order to secure the brace to the body partition, for which you will have to drill several holes.

As for the material from which spacers are made, the most common is duralumin. There are also spacers made from carbon fiber and carbon fiber. Carbon parts are quite expensive. We should not forget that installing a new part into a machine significantly increases its weight, so the spacers must be light but strong. Duralumin stretchers from Japanese manufacturers have received very good reviews, as they are quite rigid and do not tear or deform.

To make a spacer yourself, you need to be able to work with an angle grinder and other tools for working with metal. First you need to measure the diameter of the glasses between the distant bolts on which the spacer will be attached. It is advisable to use an existing spacer as a basis. In order to make an element that will be attached to the glass, you need to take a metal plate (the thickness should be 5 - 7 mm)

, and you need to put a cardboard stencil on it, which needs to be cut to the diameter of the glass after measuring all the dimensions. Next, you can apply a drawing to the metal itself using a can of paint. Using a grinder, you need to cut out one of the parts of the future spacer according to the finished drawing.

To make an inner circle, you can try cutting a hole with a grinder, or take a drill and drill circles along the entire diameter using a drill, and only then remove the unnecessary metal circle. If you decide to cut a hole with a grinder, then you need to take a diameter slightly smaller than the true diameter of the glass, so that you can then bring the circle to the required size with a file or on a sharpening disk. Based on the finished product, like a pattern, you need to make an element for the second side of the spacer. The next step will be making the frame. To do this, you need to take a 20 mm pipe 2.5 m long and bend it.

There is no point in immediately moving on to deforming the pipe. It is better to make a blank from wire, which will need to be changed according to the shape into which the pipe will then need to be bent.

Using a pipe bender, you need to change the shape of the pipe so that it fits well under the hood. The already curved work, which you must adjust to size, needs to be welded to the platforms, and on the sides of the work you need to weld 2 rectangular plates, which will make the structure more durable.

After the entire spacer is twisted, it needs to be sanded, degreased, primed and painted. Installation of the stretcher consists of screwing the platforms to the glasses. That's all. Financial costs may vary. Whether to do the spacer yourself or not is up to you. The main thing is to remember to park the car on a flat surface.

Some people consider spacers to be a cheap show-off, but some people simply need them. The choice is yours. Good luck on the roads.

Ass around the perimeter and only between the glasses

To strengthen the rear of the machine, three types of struts are used:

Single strut brace attached to the top of the rear shock absorber cups.
A rectangular “TV” located around the perimeter of the opening between the elements.
A set forming a cross-shaped structure.

These amplifiers are either unregulated or adjustable. The original rear strut strut is designated by number 21100-5601265-87. Price – 1000–1100 rubles. The lower one, from Priora, costs about the same, similar to other manufacturers.

Its installation makes it impossible to transport large items inside the cabin; when sporting a car, its cargo characteristics do not matter.

The rectangular rear strut brace includes four components:

2 horizontal (top, bottom).
2 vertical.

The parts are connected to each other at their ends, forming a rectangular structure. The upper horizontal pipe is attached to the top of the rack glasses. Bottom - to the transverse floor panel. On some models of “TVs,” quick-release upper horizontal elements are installed between the rear pillars; this helps maintain a large volume of luggage compartment when the rear seats are folded. Cost – 3700-4500 rubles.

The rear cross-shaped amplifier is present in the Lada Sport range. Article – 21100-5601260-87. Price – from 3000 rubles. Stretches of similar design are produced by many companies.

Advantages of rear body reinforcement for VAZ

Pajero mini

Of course, you can try to make a rear strut brace for a VAZ car yourself, but experts recommend using professional products, especially since they are presented in sufficient quantities on the shelves of domestic stores.

Advantages of installing the rear amplifier of the VAZ body:

The rear strut brace allows you to cope with the problem of comfortably opening car doors.
The rear body reinforcement helps reduce the level of noise and extraneous sounds in the VAZ interior.
Increasing body rigidity leads to an increase in such a parameter as the overall durability of the vehicle.
Stretching the rear pillars also leads to a significant increase in ride comfort.

A direct consequence of installing a rear strut brace (or rear strut bracing) is:

Improving vehicle stability and controllability.
The vehicle, after installing the rear strut braces, begins to obey the steering wheel better.
Any VAZ model immediately begins to respond faster to the driver’s actions, thanks to faster reaction times.

The domestic market allows you to buy several types of rear body amplifiers, the most popular of which are such options as products under the Tekhnomaster and Avtoprodukt trademarks.

The “Technomaster” product allows you to increase the rigidity of the body by almost a quarter after installation. Another plus is that the crossbar is completely removable, which contributes to more efficient use of the luggage compartment, which is not the most spacious in domestic VAZs.

The peculiarity of "Autoproduct" is that these products increase body rigidity by only 5 percent, but, in addition, reduce the movement of the rear suspension fasteners by 20 percent.

Removal and installation of all types of spacers

Almost all amplifiers of AvtoVAZ cars are installed in standard places and do not require drilling, welding, or other changes to body parts. A standard set of wrenches is sufficient. Sometimes it is necessary to use other fasteners. For example, when installing the lower part, longer than standard bolts are used.

Most manufacturers include with their products the necessary components and installation instructions, which include the following steps:

Removing standard fasteners.
Installation in place of a new part.
Fixing the structure using removed or special fasteners.

Adjustable amplifiers require pre-adjustment of the length in accordance with the actual dimensions of the car body by rotating the bushing. It is impossible to change the length of the reinforcing elements in order to influence the geometry after their installation.

Types of spacers

For spacers, you can use round pipes, or square pipes, or a rectangular profile.

There are two types according to the method of attaching the rod to the flanges:

rigid appearance, this means a welded connection;
movable type, this means articulated. The hinged connection method is more reliable, because the weld can become unusable over time.

There are three types according to the method of attaching flanges to racks:

two-point fastenings, which means that the design has at least two points of fastening to the body glasses;
three-point with intermediate fastening to the body;
three-point with engine mount.

The latter type of design additionally dampens engine vibrations.

The main disadvantage of the spacer is that if there is a strong blow to the side, the opposite side will bend through the pipe. Therefore, now factory spacers are made with notches so that during a strong impact they bend and do not destroy the opposite side.

Pros and cons of stretching the front struts

Strengthening the car's body, both front and rear, makes it stiffer. For example, the upper part of the struts reduces the movement of the suspension mounts, reduces stress at the mounting points, and increases rigidity. Thereby:

The car becomes more composed when cornering.
The maneuverability of the vehicle increases due to increased control accuracy.
Improves stability during straight-line movement.
Body deformation is reduced when driving on uneven roads.
The likelihood of fatigue cracks in metal elements is reduced.
The main disadvantage of installing reinforcement is that due to the rigid connection between the right and left parts of the car, elements on both sides are damaged in an accident.

In addition, boosters violate the vehicle's manufacturer-designed crumple zones, which impairs safety in serious accidents. Therefore, using the part for civilian use is inappropriate in most cases.

The purpose of the front, lower, rear, and other reinforcements is to increase body rigidity. This improves the driving characteristics valued in motorsports, but reduces the safety and practicality required for normal use of the car.

Why do you need a stretcher on a Priora?

Firstly, it can improve the reliability of car control when turning.

Secondly, the spacer increases the stability of the car when driving in a straight line, which is very important.

And thirdly, thanks to the increased rigidity of the body, the strength of the car increases - in fact, it deforms less when driving on uneven, bumpy roads. Due to this, the car body lasts longer.

The history of the appearance of such a detail as stretching the struts on the Priora goes back to the Soviet Union. Racers competing in rally and cross-country eights made and installed their first stretch marks. From them the fashion spread to “civilian” car enthusiasts.

One of the disadvantages of the spacer is the violation of the geometry of the side of the body, but branded products are free of this disadvantage. Also, on some cars, the spacer prevents the brake fluid from being added to the reservoir.

Advantages and disadvantages

Both research in sports and real reviews from drivers who installed the brace prove a lot of advantages of this suspension device. The main advantages of strut spacers are as follows.

The design of the car becomes more rigid, which has a positive effect on the driver’s confidence.
The turning path is clearer.
Stretching prevents premature body cracks.
When driving forward normally, the car wobbles are eliminated, and the Lada holds the road more steadily.

But there are no absolute solutions. The spacer also has disadvantages. These include the dependence of the racks on each other. If one wheel hits the tripwire, contact with the second is also ensured. To solve this problem, they are now producing spacers of a special design that bend the brace itself upon impact; the second strut is not affected.

If the front pillars are unevenly loaded, you should not install a two-point strut to level the situation: in this case, the devices will be at risk of deformation and replacement.

How to lower the Priora correctly

There are several ways to lower the landing position on the Priora. Each of them is worth dwelling on in more detail.

Air suspension

Air suspension is considered one of the best, but at the same time expensive, ways to lower a car. The driver can raise or lower the car body as necessary. In addition to the high cost of such equipment, the work must be carried out by specialists who understand the electronics and chassis of the car. Therefore, most Prior owners prefer less expensive methods of undervaluation.

Suspension with adjustable ground clearance

The Priora can be equipped with a special adjustable suspension kit. Height adjustment is carried out by means of struts, and springs with a selected lowering (-50, -70, -90) are compressed or stretched. Thus, the car can be raised for the winter and lowered for the summer. The springs that come with the kit are highly reliable and are designed to constantly change in length. The set in question consists of the following elements:

front and rear springs;
screw-adjustable struts and shock absorbers;
front upper supports;
spring cups;
bumpers.

The procedure for implementing such a kit comes down to replacing the standard suspension elements with new ones:

Remove the rear shock absorbers along with the springs.

It is recommended to lubricate the threaded part of the shock absorbers with graphite lubricant.

Lowered suspension

This method of lowering the suspension is less expensive than the previous one. It involves purchasing a set of shock absorbers and lowered springs (-30, -50, -70 and more.). The disadvantage of this kit is the impossibility of adjusting the ground clearance. However, you can install such a suspension yourself. To replace you will need the following kit:
