ST XTA height- and rebound-adjustable coilover kit with unibal top mounts for the 2008-2013 BMW M3 (E92) — designed for vehicles equipped with EDC (Electronic Damping Control) rear dampers. Front coilovers replace the OEM struts; the OEM EDC rear dampers are retained. Ride height is set via a friction-optimized polyamide composite spring perch with a stainless-steel insert; rebound damping adjusts across 16 clicks; and aluminum unibal top mounts improve steering response and allow camber adjustment where applicable. Built by hand by KW in Fichtenberg, Germany.
