ST XTA 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. For increased performance, the ST XTA features an aluminium adjustable topmount allowing the camber and caster to be adjusted depending on your driving needs or vehicle setup.
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.
The high-quality ST XTA 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.

ST's 2-way adjustable competition shock absorber is based on the ST twin tube damping system, and features independent rebound adjustment. Depending on the sealing and the adjusting of the individual kit, ST's systems may be charged with pressures of 3 to 8 bars,or without any pressure at all.
The rebound adjustment is positioned in most cases at the end of the piston rod(top of strut), extra labour will be required to adjust the rear suspension.
1st step: Place the ST adjuster on the adjustment allen bolt.
2nd step: Turn the adjuster clockwise to right until it stops. This is now adjusted to full hard(clockwise=harder).
3rd step: Turn the ST adjuster clockwise to soften the rebound setting to the desired level. The effective adjustment range is from 0-16 clicks/0-2.75 turns open.
Rebound Adjusting Principles:
In general a soft rebound adjustment provides a comfortable ride at low vechile speeds but the vechile will have less stability at higher speeds, especially on the front axle(vechile will tend to float at higher speeds). A hard rebound adjustment offers more stability but could reduce vechile grip(i.e the vechile will tend to skip across road imperfections, reducing traction).
