Notes on threaded chassis M3 GTS

The BMW M3 GTS features a threaded chassis with the following range of adjustments:
- Vehicle height
- Camber on front axle
- Rebound/compression stage, shock absorber

This can be used to adjust the chassis to different road profiles and driving styles.
The chassis has two preset setups:
- Road setup = factory setting for operation in traffic
- Racetrack setup = setting for operation on a racetrack only
Important!
For operation in traffic, the factory settings (road setup) must be used!



Note the following procedures for setting the various setups:
• Ride height
• Rebound and compression stage setting

Recommended adjustment values:
Road setup Rebound stage Compression stage Ride level
Front Axle 8 clicks open 5 clicks open 613
Rear axle 9 clicks open 4 clicks open 597
Racetrack setup
Front Axle 8 clicks open 3 clicks open 597
Rear axle 9 clicks open 2 clicks open 585
