CASTER
Moving the front or rear position of the lower control arm in or out, will change the caster angle and camber angle significantly. To maintain the camber angle while adjusting caster, move one pivot bolt of the lower control arm in or out. Then move the other pivot bolt of the lower control arm in the opposite direction.
To increase positive caster angle, move the rear position of the lower control arm inward (toward the engine). Move the front of the lower control arm outward (away from the engine) slightly until the desired camber angle is obtained.
