The ST X Coilover suspension was developed for the everyday driver who needs to hug the curves yet retain road comfort. Simple, uncomplicated road performance for those who just want to get in and drive. Add in our wide range of height adjustability; the ST X Coilover will look as perfect as it feels. ST XCoilover kits deliver precise adjustment to your ride height and look of your car. We manufacture an adjustable spring perch made of durable and friction-optimized polyamide composite material with a stainless steel insert. Thanks to the composite material corrosion is prevented between the strut and perch ensuring long lasting height adjustability. Galvanized zinc coated steel struts optimize corrosion protection for long lasting use. We add a dust protection system to prevent unwanted dirt and particulate from coming in contact with the hardened chrome piston rod or getting into the valve packs. We reinforce the system with a multi-layered pressure resistant sealing package, mono block guide system and a low friction piston band which works inside the pressure resistant internal damper housing. At ST suspensions we do not accept compromises. As a matter of principle we rely on world class engineering delivered from KW for all our dampers. Why? To simply improve your driving experience! All ST X Coilover kits are application specific for your car and perfectly adapted for everyday life.
