Another commonly modified part of sports cars or “riced” out cars is called “camber”. Camber is measure of the wheel perpendicular to the ground. Camber is measured in degrees, either positive or negative.
Positive camber is when the top of the wheel sticks further out than the bottom of the wheel. Positive camber is usually not used on vehicles because it is very dangerous. When a vehicle goes into a turn the weight is shifted onto the outside of the tire, which is a very small portion of the tire. While this helps turn-in, it also causes very dangerous loss of traction in certain situations. The only cars that use positive camber is NASCAR cars. Positive camber is also typically seen on vehicles that are not properly maintained.
Negative camber is when the bottom of the wheel sticks out further than the top of the wheel. This is seen in small amounts on every properly maintain vehicle. Unlike positive camber, negative camber actually helps provide safety in most turning situations. When a car is turning the weight is shifted to the outside edge of the vehicle, with negative camber it actually provides a wider contact patch with the road on the tire that the weight is being transferred to. Ergo, a safer turn providing more traction, equalling a faster car.
Unfortunately many ricers enjoy the look of this on a lowered car, which is sometimes called stance. Past a few negative degrees this can actually hinder the performance of the vehicle, reducing the functionality of the suspension and the safety of that vehicles.
