In recent years, a huge number of motorists have become interested in the topic of negative camber on the rear axle. There are hundreds of rumors on the Internet that in this way you can increase manageability. Now breakup plates are often advertised. Let's see if this adjustment is so useful for the average car owner.
General information
Before we begin to consider the pros and cons of a negative collapse, it is worth understanding what this collapse is and how it happens. This little educational program will be useful for novice drivers.
There are three types of camber - zero, negative and positive.
Now about each one separately. When the camber is zero, the wheel alignment angles are completely perpendicular to the ground or pavement. If the top of the car's tires are facing inward, then it is negative camber. If the top of the wheel points outwards, then a positive angle is set.
When drivingalignment parameters are constantly going astray. The wheels are heavily loaded. Angles tend to change. Often during operation it becomes noticeable that the angles on the front axle and on the rear do not match. Therefore, it is worth visiting the service station more often and adjusting the angles on the wheels of two axles. This is done on special wheel alignment stands.
If the angle settings are optimal, then the car becomes more agile and stable on the road. Even if you change the camber by only two degrees, this can seriously affect the stability characteristics. It will also affect the life of the rubber.
What is the negative camber for?
It might look like it's for style. Many have seen cars prepared for drifting or just cars with low ground clearance and camber wheels. Let's try to figure out why they do it from the point of view of physics.
This camber has a positive effect on the handling of the car. This makes it possible to enter turns at a relatively high speed. Camber in the red prevents the rear axle from skidding.
The car has three types of steering. There is insufficient, neutral, and also excessive. The last one is the most important in this case.
Oversteer
How does it manifest itself? If the wheels on the rear axle lose traction first, it's oversteer. In this case, the rear axle of the car will be demolished. Even a reversal is possible. Rear-wheel drive cars are very prone to this, it is more difficult to correct the car compared to front-wheel drive. Atfollowing the recommendations, the car is safe, but oversteer is felt on slippery surfaces.
Methods to combat this phenomenon
Positive camber is adjusted on the front axle. Rolling increases the outward tilt of the wheel. The suspension is adjusted for vertical stiffness.
One of the popular methods of dealing with oversteer on the rear axle is precisely the negative camber of the rear wheels.
A little bit about drift
For city driving, the collapse in the minus on the rear axle may not be done. But if we consider a car for drifting, then this approach is very relevant here. This allows the car to literally bite into the road. For drifting, negative camber values can range from -0.5 to -5.5 degrees. The collapse in the minus is considered optimal for circuit racing. The camber must be greater on the front axle than on the rear.
When entering a turn at high speed, the car body rolls a lot. It is at this moment that a very strong influence is exerted on the wheel. It can go into a positive collapse. This can cause a skid.
If the camber angle is -2.0 or -2.5 degrees, then body roll will not affect the wheel as much, and the car will enter the turn confidently and easily. In this case, the speed can be quite high.
Stance-culture
Speaking of negative camber, it is necessary to say about this current. This is a fashion for cars with low suspension and very heavily loaded wheels.
In these cars, as a tribute to style, huge wide wheels are installed. At the same time, the landing of the car is very low. The rims have to be so big that they might not even fit in the wheel arch. For this, they make a negative collapse. From the outside it looks spectacular, but driving comfort is reduced.
Flaws
Above we looked at the pluses of minus camber. Now let's look at the disadvantages. The inside of the tire will be subject to increased wear with this setting. Sharp acceleration and braking will not be very effective, as the contact area of the car wheel with asph alt decreases. If the car is driving on a bad road, it may be pulled to the side.
The most annoying thing is the rapid rate of tire wear. Intensive wear will occur even when the tire is installed even at a negative angle of -1 degree. The larger this angle, the faster the tire wear. Riders can afford to change tires after each race. For an ordinary car owner, such an installation of angles can be unprofitable. The driver of a civilian car will not receive special advantages in the city.
How to change the collapse?
Before you start changing angles on a car, you need to find out if such a camber is suitable for a particular model and brand and whether the vertical and lateral stability parameters of the car will be normal.
Now it's time to move on to how to make negative camber. To do this, you need to pick up plates in stores for setting wheel angles. Today theysold for any car. When choosing inserts, the desired angle must be taken into account. The choice is very large, and all the details are different. The installation algorithm is almost the same for most cars.
The machine must be raised with a jack or lift. Then the wheel is removed, then the drum or disc brake mechanism along with the pads. After that, remove the hub. Then it remains only to install the plate according to the instructions and all the previously dismantled parts. The same manipulations are done with the reverse wheel.
The procedure is not difficult, but if there are no skills, you can go to the wheel alignment, check the set angle, and then ask the specialists to install the plate on the car.

In the age of modern technology, the technical characteristics of a car provide for the presence of a large number of electronics. Cars are literally stuffed with it.

Three-wheeled scooter: two wheels in front or two wheels in back
Ten years ago, unusual motor scooters suddenly rolled out onto the roads. The three-wheeled scooter had a truly revolutionary design, where two wheels were located not in the back, but in front. Who came up with this first is unknown. But the first models, after the decline of surging emotions, did not cause much enthusiasm among consumers. New attempts are on the way. The same scooters look much more familiar, but, as expected, with two wheels at the back. Let's talk about some and other models in order

Unfortunately, despite the constant road construction, they have to work quite intensively. As a result, early failure and the need for replacement. To do this, it is not necessary to contact the service and spend additional funds. The rear struts of "Kalina" can be completely replaced on their own, sometimes even without removing
