Definition and Explanation
Ever wondered why your car’s tires seem to lean inward? That’s camber, and it plays a crucial role in handling and performance. Negative camber, a specific type, is a subtle but significant element of vehicle design. Understanding it can shed light on the engineering behind your ride.Camber, in general terms, describes the angle of a wheel’s inclination relative to the vehicle’s vertical axis.
Think of it like tilting a wheel slightly inward or outward. This seemingly small angle has a surprisingly large impact on how your car behaves on the road.Negative camber is distinguished by the wheel’s tilt inward, towards the center of the vehicle. In contrast, positive camber tilts the wheel outward. Zero camber means the wheel is perfectly perpendicular to the vertical axis.
