The ST XTA coilover kit (18258804) is a height- and rebound-adjustable suspension system for the 2013-2020 Scion FR-S, Subaru BRZ, and Toyota 86. Hand-built by KW in Germany, it pairs galvanized zinc-coated monotube struts with 16 clicks of rebound damping and aluminum unibal camber-adjustable front top mounts, so you can dial in ride height, damping, and front camber. A linear race spring system and friction-optimized composite spring perches keep adjustment smooth and corrosion-free over time.
