Wheel Alignment Angles: Camber
The three basic alignment angles are camber, caster and toe. Camber and toe affect tire wear and directional stability, caster affects directional stability only. Camber, caster and toe settings change when the vehicle is loaded. The specifications given in this article are static settings with the vehicle unloaded.
Camber is the inward or outward tilting of the wheels at the top. When the wheels tilt out at the top the camber is positive (+). When the wheels tilt in at the top the camber is negative (-). The amount of camber is measured in degrees from vertical.
Steering axis inclination (included angle) is the center line drawn through the ball joints when viewed from the front.
