ST Suspension ST X Adjustable Suspension Kit for BMW F23 F30 F32 F36 RWD

Give your BMW F Series the stance, control and confidence it deserves with the ST Suspension ST X adjustable suspension package. Developed with KW Automotive know-how, this coil-over system blends everyday comfort with sharp, predictable handling for fast road use, commuting and the odd track session. Expect precise ride-height control, cleaner turn-in and that purposeful, level look enthusiasts want.

We run ST X on our own cars and feedback from our customers is consistently positive. Ride quality is composed, cornering grip is markedly improved and the drop is even and usable. If you want a quality German-engineered upgrade without complication, this is a proven choice.
