ST XTA height-adjustable coilovers for the 2007-2013 BMW 328i, 335i and 335is. The kit pairs a linear race spring system with adjustable rebound damping and aluminum unibal camber-adjustable top mounts, so you can set both ride height and front camber to dial in wheel and tire fitment. Each damper is built by hand at KW in Fichtenberg, Germany, and shock-dyno tested to factory settings before shipping. The 16-click rebound adjustment lets you tune the car from comfort to sport, while the galvanized zinc-coated steel struts and composite spring perch with stainless-steel insert resist corrosion for long-lasting height adjustability.
