Description

The ST XA Coilover Kit provides height adjustment and individual damping adjustment to fine-tune driving behavior for enhanced road control without compromising comfort. It features 18 distinct clicks of adjustable rebound damping, allowing drivers to make the suspension stiffer or softer. The lowering adjustment is made via a continuously threaded strut housing on the galvanized strut, even while installed. These coilovers are developed by KW Automotive and are based on a twin-tube damping principle with low-friction, pressure-resistant damper housings. They are manufactured by hand at KW in Fichtenberg, Germany, and each damper is tested on a shock dyno.
