Developed with KW Automotive
The ST XA coilover uses proven KW damping technology and a robust twin-tube design with pressure-resistant housings. The rebound adjustment is conveniently located at the top of the chromed piston rod, so you can quickly dial in a firmer, more controlled ride for spirited driving, or soften for comfort on rough roads. Each strut is galvanised and sealed multiple times to keep performance consistent mile after mile.
