ST XA Coilovers - KW Quality, Adjustable Performance for the Road

Take control of your vehicle's ride height and suspension characteristics with ST XA coilovers.

Product Notes

  • Vehicles equipped with factory electronic damping require a deactivation kit, please select 'Cars With Electronic Dampers' to include this in delivery.

Unlike a conventional fixed damping coilover, the ST XA allows you to fine tune the rebound damping to suit your preferences. The supplied dampers feature a vehicle specific base setting, giving you a balanced starting point straight out of the box. From there, the 16-stage adjustment allows you to alter the damping characteristics towards a firmer, sportier setup or a more compliant and comfortable road going feel.The continuously adjustable ride height allows you to fine tune your vehicle’s stance within the approved adjustment range, making it possible to achieve the look and wheel fitment you want. The adjustment system uses a durable, dirt resistant trapezoidal thread and composite spring perches with stainless steel inserts, helping maintain reliable height adjustment while offering excellent corrosion resistance.


ST XA coilovers are equipped with progressive moulded springs, providing a useful balance between comfort and handling. The initial section of the spring is comparatively soft, allowing the suspension to respond more sensitively to smaller road imperfections. As the suspension compresses further, the spring rate increases to provide greater support during harder cornering and more aggressive driving.

Durability has also been considered throughout the design. The coilover bodies feature galvanised and multi sealed steel strut housings for improved corrosion protection, while integrated dust protection helps prevent dirt and water from reaching the damper seals. Bump stops provide additional support when the suspension is subjected to heavier loads.

With its vehicle specific damper calibration, progressive springs and corrosion resistant construction, the ST XA provides a versatile coilover package that combines stance, handling and adjustability in one system.
