31 .. ... Threaded Suspension



31 .. ... Threaded suspension M3 GTS setting







NOTE: The traffic setup meets the factory setting for the operation in traffic. If the suspension setting was changed, then you must make sure to change the ride height to normal position before operation in traffic.







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







A hook wrench for turning the spring cup is included in the toolkit.
(1) = adjuster for front axle
(2) = adjuster for rear axle







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

Camber and toe values may only be adjusted in the ride height "road operation".
