ST XA Height & Rebound Adjustable Coilovers for 2006-2013 BMW 325i, 328i, 330i, 335i, and 335is - 18220032

Fits 2006-2013 BMW 325i, 328i, 330i, 335i, and 335is (Base models).

Engineered for drivers who want to influence more than just ride height, the ST XA coilover system offers a wide range of height adjustment combined with 16 clicks of adjustable rebound damping. This system allows you to precisely dial in your BMW's driving behavior, achieving enhanced road control and reduced body roll without sacrificing daily comfort. Built by hand by the suspension experts at KW in Germany, each damper is tested on a shock dyno to ensure consistent performance and proper damping forces.

Construction features galvanized zinc-coated steel struts for long-term corrosion resistance. The adjustable spring perches are manufactured from a wear-resistant, friction-optimized polyamide composite with a stainless steel insert, preventing the oxidation and seizing common with traditional aluminum perches. A complete dust protection system—including elastomer bump stops and integrated seals—shields the hardened chrome piston rods from road debris and moisture.
