Perfect for sporty driving

ST XA coilovers feature KW damping technology which allows the suspension to be made either stiffer or softer depending on the driving conditions. This damping adjustment is made on the upper end of the chromed piston rod allowing the setup to be changed almost instantly. If the rebound force is increased, the car will drive with more track stability and reduced body roll. If the rebound force is decreased, the car will feel more comfortable on the move. Any vehicle fitted with ST XA coilovers will behave much more agile and sporty compared to stock.

Easy lowering adjustment

With all ST coilovers, the lowering adjustment is made via a continuously threaded strut housing on the galvanized strut. This even allows the lowering to be made even when the kit is installed by turning the spring perch higher or lower! NOTE: The lowering of each vehicle differs greatly with ST XA coilovers due to the types of suspension construction.

KW Engineering: Exclusive for ST suspension

The high-quality ST XA coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a monoblock guide and multi-lip sealing package reduce the friction of the damper as well as protects it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity
