The ST XA coilover kit for 2000–2003 BMW M5 (E39) offers wide height adjustability and fine-tunable damping to sharpen handling without sacrificing daily comfort. Built and tested by KW in Germany, each damper is verified on a shock dyno, shipped with factory-recommended settings, and provides 16 distinct rebound clicks. The kit uses a corrosion-resistant composite spring perch, galvanized struts and integrated dust protection for longevity.
