The ST X coilover kit delivers height-adjustable suspension for the 8V Audi A3 and S3 Quattro, tuned to balance sportier handling with daily-driver road comfort. Dampers are application-specific, valved by KW's vehicle-dynamics engineering and built by hand in Germany. The kit uses galvanized zinc-coated steel struts and a friction-optimized polyamide composite spring perch with a stainless-steel insert for corrosion-resistant, long-lasting ride-height adjustment.
