Suspension Strut / Shock Absorber: Adjustments

31 .. ... Rebound and compression damping setting shock absorber M3 GTS







NOTE:
The setting of the compression stage exerts significant influence on handling and drivability.
Low rebound forces improves the ride comfort during a slower journey, yet with according setting reduces the stability and turning precision during faster journeying.
High rebound forces further improve the handling on the front axle, but possibly at the expense of the adhesion. The ride comfort will be greatly reduced.







IMPORTANT: The adjusting spindle operates a precision mechanical valve. The end of the adjustment range must not, under any circumstance, be exceeded, otherwise the setting mechanics can become damaged.

Never combine rebound and compression stages in such a way that one axle is completely hard and the other soft, this leads to adversely affected driving stability and can thereby lead to accidents.







NOTE: All settings are to be taken based on the closed valve condition. In addition, turn the adjusting spindle right until the limit position.







Front axle setting:
Adjust rebound:
- Remove shock absorber cover
- Insert knurled screw (1) into piston rod damper
- Adjust rebound (1) by turning of knurled screw
See recommended adjustment value







Adjust compression stage:
- Adjust compression stage by turning of knurled screw (1) on damper underside.
See recommended adjustment value.






Adjust rear axle:
- Remove luggage compartment trim panel
- Insert knurled screw (1) into piston rod damper and adjust rebound.
See recommended adjustment value.







NOTE: Compression stage setting on removed damper described.

Adjust compression stage:
Pull off dust cap (1).







Adjust compression stage by turning to left/right with needle-shaped adjusting pen (1) (contained in toolkit).
See recommended adjustment value.
