    ST X Screw Set

    Give your car a completely new look and improve driving characteristics with the ST X coilover kit. This kit was developed in collaboration with KW Automotive, the expert in suspension systems. The result? A perfect combination of German reliability, sporty handling, and the freedom to determine your own ride height.

    Why the ST X series:
    The ST X coilover kit is the ideal choice for those who want more than just lowering springs. While standard shock absorbers are often not designed for a significant lowering, this set is fully matched for harmonious handling.

    1. Infinitely adjustable: Thanks to the robust screw thread on the galvanized struts, you can adjust the height of your car with millimeter precision.
    2. Material: Made of high-quality galvanized steel with an extra protective coating against corrosion.
    3. Sporty comfort: The damping is optimally tuned from the factory for a sporty driving experience without sacrificing everyday comfort.
    4. Superior quality: The shock absorbers feature a high-quality coating for maximum protection against corrosion, even under severe weather conditions.
    5. Direct handling: Experience less body roll in fast corners and a shorter braking distance due to improved stability.
    6. Certified safety: Fully TÜV-approved, guaranteeing a safe and legal lowering.

    Upgrade your car with KW technology for a fraction of the price. Whether you go for an aggressive look on the track or precise handling on public roads, you never make a wrong choice with the ST X coilover kit.
