Simultaneous deletion (addition) one or more washers of the same thickness in the front and rear packages only change the camber (this causes wheel alignment to be lost) and practically does not affect the angle of the longitudinal inclination of the axis of rotation. So, the simultaneous installation of washers with a thickness of 0.5 mm in the front and rear packages gives a decrease in camber by 7-9', and vice versa.
The camber angle is determined by the difference in distances from the plumb line to the upper and lower points of the wheel rim. A difference of 3 mm corresponds approximately to a camber of 30'.
Using a caliper or ruler, we measure the distance from the plumb line to the upper and lower points of the wheel rim.
