KW’s ClubSport suspension for the F80/F82 M3/M4 is created with track day and driving school enthusiasts in mind. The ClubSport suspension retains the stainless steel damper found in the Variant 3 but replaces the standard progressive rate springs with linear rate springs for crisper turn-in and more consistent suspension response. The ClubSport suspension gives a wide range of lowering adjustment, damping adjustment in rebound and compression, and front camber plates with a sealed bearing for front camber adjustment. An EDC module is available for an additional charge and will cancel any error codes caused by removal of the factory EDC suspension.
