BMW Performance Parts

Activating the M Dynamic Mode and Dynamic Stability Control (DSC) gives your sports ambitions free rein. Drive slip for both longitudinal and transverse dynamics increases at all speed levels because DSC does not instantly intervene in the automobile's motion. For those people who did not select the M-Drive option when ordering your M3, or if you happen to get one used without it - this will give you the option to push your M3's handling limits without the danger of completely losing control.
