Looking for maximum performance for your car? Our adjustable ST XTA Coilover kits are the upgrade you need. All ST XTA systems are delivered with a linear race springs system, adjustable dampers, and aluminum unibal camber adjustable top mounts. ST XTA Coilover kits deliver precise adjustment to your ride height so you control the look of your car. We manufacture the 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 while the stainless steel insert provides strength and confidence! ST XTA Coilovers come preset to our factory recommended damper settings, the same configuration we test them at on our KW shock dynos before they go into your box. The 16 distinct clicks of adjustable rebound damping allow you to refine the driving dynamics with a simple turn of the adjustment knob. Each kit includes a detailed damper setup manual making it easy to reset to our recommended setting at any time. Whether your preference is comfort, performance, or something in between; ST XTA puts the finer details of the driving dynamics in your hands. The top mounts included with our ST XTA Coilover kits allow you to adjust the camber at the front axle to dial in aggressive wheel and tire fitment. They also allow you to maximize the tire's contact patch for driving in fast corners and any other driving scenario that demands maximum grip. 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.
