ST Suspensions X Coilover Kit – 2000–2006 Audi TT / TT Roadster Quattro (8N)

Lower your 8N Audi TT and improve handling without sacrificing daily drivability with the ST Suspensions X Coilover Kit. The ST X is engineered for the everyday driver who wants improved cornering performance, a lower stance, and a more connected driving feel — without the harshness of a track-focused setup. Built on KW-engineered dampers and featuring a wide range of ride height adjustability, the ST X delivers a balanced street performance upgrade that looks as good as it drives.

Key Features

• KW-Engineered Dampers: All ST X damper internals are engineered by KW — world-class suspension engineering delivering precise, consistent damping performance for street use
• Ride Height Adjustability: Wide range of ride height adjustment via an adjustable spring perch — dial in your preferred stance without compromising suspension geometry
• Polyamide Composite Spring Perch: Adjustable spring perch manufactured from durable, friction-optimized polyamide composite with a stainless steel insert — prevents corrosion between the strut and perch for long-lasting, smooth height adjustability
• Galvanized Zinc-Coated Struts: Galvanized zinc coating on steel struts provides optimized corrosion protection for long-term durability in all weather conditions
• Dust Protection System: Integrated dust protection prevents dirt and particulate from contacting the hardened chrome piston rod or entering the valve packs — extending damper service life
• Multi-Layer Sealing Package: Pressure-resistant multi-layered sealing package, mono block guide system, and low-friction piston band for consistent, reliable damper performance
• Street-Comfort Oriented: Developed for the everyday driver — improved handling and lowered stance without the ride harshness of a track-focused coilover
• Application-Specific Tuning: Each ST X kit is application-specific and tuned for the 8N TT platform — not a generic universal kit
