ST Coilover Kit 00-06 Audi TT/TT Roadster Quattro (8N)

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. The ST X Coilover system is the ideal mix of sportiness and simplicity while still maintaining some comfort on the street. The wide range of ride height adjustability allows you to fine tune your tire and wheel fitments. 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. 2000-2006 Audi TT & TT Roadster (8N) Quattro 1.8T (4cyl.)

• Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability.
• Composite spring perch made from wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. The polyamide composite prevents oxidation while the stainless-steel insert maximizes strength.
• ST X coilovers are the ideal mix of sporty yet simple. The dampers and spring rate come tuned by our vehicle dynamics engineering in Germany to perfectly match each vehicle specific application.
• ST coilovers are built by hand by the experts at KW in Fichtenberg, Germany. Each damper is tested on a shock dyno to verify it's making the proper forces before being put into the ST box.
• Seamless Ride Height Adjustment - ST's composite spring perch and unique trapezoidal thread pitch make ride height adjustability a breeze so you can dial in your preferred look.
• Galvanized steel housing for improved resistance to corrosion.
• 5 Year Limited Warranty - Unlimited Mileage
• Made in Germany
