ST XTA height-adjustable coilovers for the 2008-2013 BMW 128i, 135i and 135is (E82/E88). The kit pairs a linear race spring system with 16-click adjustable rebound damping and aluminum unibal camber-adjustable top mounts, so you set ride height, damping feel and front camber. Built by hand by KW in Fichtenberg, Germany and dyno-tested before boxing, the galvanized zinc-coated steel struts run a friction-optimized polyamide composite spring perch with a stainless-steel insert for corrosion-free, long-lasting height adjustment.
