ST XA-Height Adjustable Coilovers 12+ Audi A3 incl. Sportback (8V) Quattro

For all those who want to influence more than just their ride height. ST XA Coilovers deliver the look you need through a wide range of height adjustment. With an extensively adjustable damper setup, you can precisely adjust the driving behavior of your car to achieve enhanced road control without a compromise in comfort. ST XA Coilover kits deliver precise adjustment to your ride height and 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 XA Coilovers come preset to our facto ry 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, sportiness, or something in between; ST XA puts the finer details of the driving dynamics in your hands. 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. ST XA Coilovers deliver the look you need through a wide range of height & damping adjustment. Precisely adjust the driving behavior of your car to achieve enhanced road control without compromising comfort. ST Coilover Kits enable you to individually adjust the ride height of your car to improve the appearance and driving behavior. Depending on your selection, ST coilover kits offer a wide range of adjustments giving you the tools needed to dial them into your requirements. 2015-2020 Audi A3 (8V) Quattro 2.0T (4cyl.)
