Like the front anti-roll bar, the rear anti-roll bar can be adjusted in seven positions,
each position resulting in a 15° change of the bending lever. Maximum stiffness of
the anti-roll bar is achieved when the bending lever is arranged parallel to the anti-roll
bar link. Minimum stiffness is achieved when the bending lever is at a 90° angle to
the anti-roll bar link.
