Rear Suspension

REAR SUSPENSION




The rear suspension is the integral - link design carried over from the E39 540i with the following modifications:
- The lower control arm is taken from the E39 sport wagon.
- The integral link is taken from the E38 - 75OiL axle in order to absorb the higher braking forces.
- The springs and shocks are specifically tuned for the driving dynamics of the M5.
- The suspension mounting bushings are reinforced to improve wheel control.
- A 25% locking differential is used with a final drive ratio of 3.15 : 1.
- The final drive cover incorporates the differential breather and cooling fins.

Alignment points on the rear suspension are the same as the E39 sedan with camber adjustments on the upper link and toe-in adjustments on the lower control arm eccentric.
