The ST XA coilover kit gives the Scion FR-S, Subaru BRZ, and Toyota 86 adjustable ride height plus 16-click adjustable rebound damping, so you can dial in handling from comfort to sport with the turn of a knob. Each strut uses galvanized zinc-coated steel for corrosion resistance and a friction-optimized polyamide composite spring perch with a stainless-steel insert for long-lasting height adjustability. ST coilovers are hand-built by KW in Fichtenberg, Germany, and every damper is shock-dyno tested before boxing. Kits ship preset to the factory-recommended damper settings with a detailed setup manual.
