What this kit delivers
The ST XA coilover kit lets you dial in your BMW exactly how you want it. Stiffen the rebound for razor sharp response and maximum track stability or soften it for long-distance comfort without sacrificing control. Thanks to continuous ride height adjustability, you can achieve the perfect stance and improve centre of gravity for better grip and confidence in every corner. Expect faster steering response, reduced body roll, and a more planted feel compared to factory suspension.
