The ST X coilover kit for 2005–2011 Audi A6/A6 Quattro (4F/C6) Sedan balances sporty handling and street comfort while offering generous ride-height tuning. The system uses a friction-optimized composite spring perch with stainless-steel insert, galvanized zinc-coated struts and a multi-layer dust protection and sealing package. Dampers are handcrafted and dyno-tested by KW in Germany; adjustment is simplified by a trapezoidal thread pitch.
