KW H.A.S. Height Adjustable Lowering Springs - BMW M3 G80 / M4 G82 (2021-2027)
If your G80 M3 or G82 M4 shocks are still in good shape and all you want is proper height, you do not need a full coilover kit. The KW H.A.S. is built for exactly this situation: spring upgrade, height adjustability, no shock swap required.
The H.A.S. system replaces your factory springs with KW units that include an adjustable perch. That perch is the key difference over standard lowering springs. You set your final ride height within the available range during installation rather than getting locked into a single fixed drop. Your factory dampers stay in place, and the G-chassis suspension tuning BMW put into the G80 and G82 works exactly as intended. Quality springs, adjustable stance, no compromise on ride.
