Product Description

The AST 5100 Clubracing Coilover Set (ACC-B2103S/5D) is a premium height- and damping-adjustable suspension upgrade engineered to dramatically enhance the handling and ride quality of BMW M3 (F80) and M4 (F82/F83) platforms. Whether you’re carving canyon turns, cruising daily roads, or pushing limits on the track, these monotube coilovers deliver superior body control, reduced dive/squat, and customizable damping feedback through a 12-position rebound adjustment. Fully equipped with camber-adjustable front top mounts and solid rear mounts, this kit gives you the tools to dial in grip, ride height, and chassis balance for both road and competition use.
