Caster Check
The nominal caster angle is 5.2°. It may be checked by mean of a standard electronic
setup bench for road cars. It is recommended not to modify it, unless extreme deviation
(> 2°) from the nominal is found.
Adjustment could only be done by changing the spacers distribution on the suspension
joints.
9.2.4.
Camber Adjustment
The wheel camber angle may be adjusted by moving the lower pivot points of the lower
arm. This is done by adjusting the cam-shaped bolts of the pivots. Remember to always
adjust the 2 cam-shaped bolts of the same arm in the same position, to avoid bending
stress and hysteresis on the suspension.
The following table is referred to the right suspension viewed from the rear or the left
suspension viewed from the front. The
angle
is the rotation angle of the cam-shaped bolt,
