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!

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 on the front suspension. 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.

Easy lowering adjustment

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! 

Front/Rear Lowering: 20mm-50mm

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 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.

  • External damper adjustment to the front suspension only(extra labour will be required for rear adjustment of suspension)
  • Latest damping technology for maximum longevity
  • Reduced system friction for effective damping adjustment
  • Individual lowering within the TÜV-tested adjustment range
  • Front and rear axle (when possible) with thread adjustment
  • Galvanized coilover struts with additional coating for an optimized corrosion protection
  • Complete solution with adjustable spring plate, race spring system and bumpers with dust protection

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. 

Adjusting Rebound:

The rebound adjustment is positioned in most cases at the end of the piston rod(top of strut), extra labour will be required for rear adjustment of 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).
