From now on you can customize your ST suspensions coilover kit and adapt it to your individual needs. For example you can select your favourite spring colour out of many options or add an additional marking on the springs. For an additional individualization of your spring setup ST also offer optional racing spring kits in different spring rates and lengths for their XTA coilover kits.

Lowering has never been so individual!

For drivers wanting more than just ride height adjustment comes the ST XA coilover. Developed alongside KW Automotive the ST XA allows individual adjustment of the damping to suit just about all your driving needs!

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 even more track stability and further reduced bodyroll. If the rebound force is decreased, the car will feel more comfortable when on the move. Any vehicle fitted with ST XA coilovers will act much more agile and sporty compared to standard.

Like all ST coilovers the lowering adjustment is made via a continuous thread on the galvanized strut. This even allows the lowering to be made even when the kit is installed by turning the spring plate higher or lower! NOTE: The lowering of each vehicle differs greatly with ST XA coilovers due to the type of construction. For example, older vehicles such as the Honda Civic (EJ9) can be lowered between 40-75mm with ST XA coilovers, while newer models such as the Audi S3 (8P) can be lowered between 10-40mm due to being much lower from the factory.

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 mono block guide and seal package reduces the friction of the damper as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions.
