Camber angle is one of the angles made by the wheels of a vehicle, specifically the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear. It is a measurement of the centerline of a vehicles wheel (and tire) relative to the road surface, provided it is even. Camber angle alters the handling qualities of some suspension designs; in particular, negative camber improves grip in corners, especially with a short long arms suspension. This is because it places the tire at a better angle to the road, transmitting the centrifugal forces through the vertical plane of the tire rather than through a shear force across it. Proper management of camber angle is a major factor in suspension design and must incorporate not only idealized geometric models but also real-life behavior of the components, such as flex, distortion, and elasticity. Camber angle has a heavy impact on the vehicles suspension design, on the grip of the tires, as well as on its driving behavior such as steering, braking, or acceleration.
