ST XA Height & Rebound Adjustable Coilovers 01-06 BMW 3 Series / E46 M3 Coupe/Convertible

If you're looking to dial in the stance and handling of your 2001-2006 BMW M3 Coupe or Convertible, the ST XA Coilover system is a solid choice. These aren't just about lowering your car; they give you the ability to fine-tune both the ride height and the damping characteristics, letting you match the suspension's behavior to your driving style and road conditions.

The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination is smart because the composite material helps prevent corrosion between the perch and the strut body, ensuring that you can still adjust the ride height even after years of use. The stainless steel insert adds strength where it's needed. Each damper is built by hand at KW in Germany and tested on a shock dyno before it ships, so you know they're performing as expected. You get 16 distinct clicks of rebound damping adjustment, controlled by a simple knob, allowing you to make the car feel more comfortable for daily driving or sportier for spirited runs. The galvanized zinc-coated steel struts offer good corrosion protection, and an integrated dust protection system keeps dirt and debris away from the hardened chrome piston rod and internal seals.

This kit comes preset to factory-recommended damper settings, and a detailed manual is included to help you reset them if needed. You'll also find elastomer bump stops with integrated dust protection, which help limit suspension travel while maintaining ride quality. Everything needed for installation is included, and the German manufacturing ensures a well-built product.
