    ST XA Screw Set

    Are you looking for that perfect lowering without compromising on ride quality? With the ST XA coilover kit, you combine an impressive lowering with the refined damping technology from KW Automotive. Whether you want to corner tightly or drive comfortably to work, you determine the character of your car through the adjustable firmness.

    Why the ST XA:

    1. Adjustable Firmness (Rebound): Thanks to the adjustable 16-click rebound damping, you can easily adjust the ride behavior. Set the dampers stiffer for more stability and less body roll, or softer for extra comfort on poor road surfaces.
    2. Stepless Lowering: Determine your own ideal ride height within the TÜV-approved range. From a subtle lowering to an aggressive, sporty look.
    3. Top German Quality by KW: The damper technology comes directly from KW. The sets utilize a double-tube damper principle and low-friction housings for a long service life and consistent performance.
    4. Durability: The shock absorbers are made of high-quality galvanized steel. This robust base is multi-sealed and optimally protected against corrosion, ensuring your set continues to perform season after season.
    5. Easy Installation: The ST XA is designed to fit perfectly onto your car's original top mounts, keeping installation straightforward.

    Choose the quality of KW, with the accessibility of ST. Transform your handling and give your car the stance it deserves!
