The ST XA coilover kit gives RWD BMW F22/F23 2-Series and F30/F32 3- and 4-Series owners adjustable ride height plus 16-click adjustable rebound damping, so you can dial in the stance and tune driving dynamics from comfortable to sporty. Each kit is hand-built by KW in Fichtenberg, Germany and dyno-tested before shipping. Galvanized zinc-coated steel struts, a friction-optimized polyamide composite spring perch with a stainless-steel insert, and a multi-layer sealing package with dust protection deliver long-lasting corrosion resistance and ride quality.
