KW DDC plug & play coilover kit for the 19+ BMW Z4 M40i (G29) / Toyota GR Supra (A90). DDC (Dynamic Damping Control) is KW’s electronic coilover: it ties into the car’s factory electronic-damper wiring so damping is adjusted on the fly through the OEM drive-mode buttons or the KW DDC app, with adjustable ride height as well. 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; made in Fichtenberg, Germany. For models with factory electronic dampers; includes DDC ECU.
