General Description


Wheel alignment refers to the angular relationship between the suspension attaching parts, the wheels, and the ground. Proper alignment is considered essential for efficient steering, good directional stability, and to prevent abnormal tire wear. The most important factors of front wheel alignment are caster, camber and toe-in.
