The ST XA coilover kit delivers ride-height adjustment plus 16-click adjustable rebound damping, letting you dial in driving dynamics from comfort to sport with a turn of the knob. Built by hand at KW in Fichtenberg, Germany, each damper is dyno-tested before it leaves the factory. Galvanized zinc-coated steel struts, a composite spring perch with stainless-steel insert, and a multi-layer sealing package provide long-lasting corrosion resistance and durability. Fits BMW 2-, 3-, and 4-Series across the F22/F23, F30, and F32 chassis.
