Setting ride height race set-up (M4 GTS only)

NOTE: The street set-up corresponds with the factory setting for the traffic. If the suspension setting was changed, then you must make sure to change the ride height to NORMAL POSITION for the traffic.

The ride height adjustment for the street setup is adjusted with C-clips (2). C-clips are installed between the spring cup (3) and the stop ring (1).

C-wrenches (1) for rotating the spring plate are included in the tool kit.

Attention! 

Make sure the springs do not lose their preload; it may be necessary not to twist the spring plate completely to the limit of the stop ring.

After setting the ride height (race/street setup), in order for the chassis and suspension to be optimally adjusted, the damping action (compression stage and rebound settings) must also be adjusted for the ride height.

Refer to NOTES ON CHASSIS AND SUSPENSION .

After the setting to "racetrack setup", the dampening setting (rebound and compression stage) is also to be performed.

Refer to NOTES ON CHASSIS AND SUSPENSION .

After the setting "racetrack setup" no wheel alignment/setting is to be performed. The camber and toe values result automatically from the height adjustment!

Camber and toe values may only be adjusted in the "street set-up" ride height.

Refer to TECHNICAL DATA adjustment values.
