ST XA Coilover Kit 00-03 BMW M5 E39

The ST XA Coilover kit for your 2000-2003 BMW M5 E39 uses a spring perch made from a durable, friction-optimized polyamide composite with a stainless steel insert. This design prevents corrosion between the strut and perch, ensuring that you can adjust your ride height for years to come, while the stainless steel insert provides the necessary strength. These coilovers are built by hand by the experts at KW in Germany, and each damper is tested on a shock dyno before it's boxed up, so you know you're getting a well-built part right out of the box.

With 16 distinct clicks of adjustable rebound damping, you can easily fine-tune your M5's driving dynamics to match your preference, whether that's a sportier feel for spirited driving or a more comfortable ride for daily commutes. The galvanized zinc-coated steel struts offer solid corrosion protection, and an integrated dust protection system keeps dirt and debris away from the hardened chrome piston rod and valve packs. This attention to detail in the internal damper construction, including a multi-layered sealing package and low-friction piston band, helps ensure long-lasting performance.

This kit allows for seamless ride height adjustment thanks to the composite spring perch and a unique trapezoidal thread pitch, making it straightforward to dial in your desired stance. The 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 act as dynamic load limiters while helping to maintain ride quality and durability.
