Non-adjustable Sachs dampers are fitted to the rear axle.
The rear anti-roll bar has a 7 position adjustment range on both sides,
each position results in the blade being adjusted by an angle of 15°. The
maximum stiffness of the anti-roll bar is achieved when the blade is
aligned parallel to the anti-roll bar link. The minimum stiffness is achieved
when the blade is aligned at 90° to the anti-roll bar link.
Always use suitable tools to rotate the blade as incorrect tools can cause
damage. Notches or other damage can cause the blade to break.
I In the following diagram the component stiffness of the rear ARB
dependent on blade position is represented:
