KW V3 coilover kit for the 19+ BMW Z4 M40i (G29) / Toyota GR Supra (A90). The V3 gives independently adjustable rebound (TVR-A) and compression (TVC-A) damping plus adjustable ride height, so rebound and low/high-speed compression can be set separately to tune steering, grip and body control without compromising one for the other. Spring and damper tuning is developed per vehicle on the Nordschleife and KW’s 7-post rig. INOX-LINE stainless struts resist corrosion for life; each kit is hand-built and dyno-tested in Fichtenberg, Germany. For models with factory electronic dampers.
