The curve of rally car is complicated, so the steering wheel angle is designed to be 240 degrees, which is very compact and can cope with continuous cornering. Drift racing car changed the steering wheel to 540 degrees in order to hit the direction quickly and control accurately.
The setting of negative inclination angle can better solve the problem of grip when cornering. The inclination angle of the tire refers to the angle of the wheel when viewed from the front, which can only be seen on some modified cars or racing cars. We usually say that the outer eight refers to the negative dip angle and the inner eight refers to the positive dip angle.
It is ideal if the car is close to the bottom inclination angle of 0 when going straight, and the negative inclination angle helps the corner when turning. Therefore, there is a special design of camber gain in automobile suspension.
