Rear Suspension
Rear Axle- To obtain greater camber (up to - 3° 30') for motorsports use, the slot in the rear axle side part near to the camber arm is longer.
The stroke of the camber eccentric is 2 mm longer to provide a greater adjustment range.
The rubber metal mounts (subframe mounts) on the side parts are harder.
- The rubber metal mounts for arms 5 (lower A-arm) and 4 (caster arm) are also harder than on the standard vehicle.
- The stabilizer, diameter 20 mm, has three adjustment positions. The vehicle is delivered with the stabilizer in the central p0sition (arrow).
The stabilizer position must not be changed for normal road use.
Caution: The stabilizer position must only be changed for racing use. For use on public roads, the stabilizer must be set to the standard position.
- The spring strut mount is equipped with a Unibal joint.
- The rear axle spring strut is equipped with a threaded sleeve and an adjustment nut (no.1) for height adjustments. In addition, the stabilizer block (no.3) (support for stabilizer mount) is attached to the thread. The height of the stabilizer block is adjustable and it is equipped with a lock nut (no.2).
The stabilizer block must only be adjusted for racing purposes. The purpose of adjustment is to ensure that sufficient space is still available for the stabilizer mount if the vehicle height is changed (only for racing) and that the stabilizer mount can be installed without stress. With the vehicle height specified for road use (see page 44 - 3), the stabilizer block does not need to be adjusted.
The stabilizer block is also correctly adjusted for replacement shock absorbers (dimensions B and C).
Note:
If lock nut no.2 is unscrewed (normally not necessary), a normal hook wrench is required. The tightening torque is 100 Nm (73.7 ft lb). Using a normal hook wrench, it is only possible to apply about 50 Nm (36.9 ftlb). In this case, an extension (tube) must be inserted into the hook wrench.
Higher torque values up to about 200 Nm (147.5 ftlb) will cause no damage whatsoever to the thread.

Dimension A = Pre-setting for production (182 ± 1 mm). For the specified vehicle height, the actual dimension may be different. If the shock absorber is replaced, the actual dimension must be transferred to the new part.
Dimension B = 147.5 ± 0.5 mm
Dimension C = 110.5 degrees
