Take control of your vehicle's driving dynamics with the ST XA Coilover kit. Engineered for drivers who want to customize more than just ride height, the ST XA series features 16 distinct clicks of adjustable rebound damping. This allows you to fine-tune the balance between track-inspired handling and daily driving comfort with a simple turn of the adjustment knob.

Built by hand in Fichtenberg, Germany by the suspension experts at KW, these coilovers utilize galvanized zinc-coated steel struts for superior corrosion resistance. The unique composite spring perch, reinforced with a stainless steel insert, ensures the height adjustment remains easy to operate even after years of exposure to the elements. Every damper is tested on a shock dyno to verify precise force delivery before it is boxed.
