The ST X coilover kit is a ride-height-adjustable suspension built for daily-driven VW MK1 chassis, pairing sporty handling with everyday road comfort. Dampers are non-adjustable and tuned by ST's vehicle dynamics engineering in Germany for this specific application, with spring rates matched to the car. Galvanized zinc-coated steel strut housings and a friction-optimized polyamide composite spring perch with a stainless-steel insert resist corrosion for long-lasting height adjustability, while an elastomer bump stop with integrated dust protection shields the chrome piston rod from dirt and water. Built by hand and shock-dyno tested by KW in Fichtenberg, Germany.
