ST XA Coilover Kit for Audi A4 (B8/B9) - Height & Rebound Adjustable

At Eurozone Tuning, we pride ourselves on offering premium suspension solutions that deliver exceptional performance and reliability. The ST XA Coilover Kit is the ultimate upgrade for Audi A4 (B8/B9) owners who want to enhance their vehicle's handling, stance, and overall driving dynamics. Developed with KW Automotive technology, this kit offers adjustable ride height and rebound damping to suit your driving style, whether on the street or the track.

Why Upgrade?

The factory suspension on the Audi A4 is designed for comfort but may lack the precision and adjustability desired by performance enthusiasts. The ST XA Coilover Kit allows you to fine-tune your car's ride height and damping settings, providing improved cornering stability, reduced body roll, and a more aggressive stance—all while maintaining everyday drivability.

Key Features:

  • Height Adjustable: Achieve the perfect stance with precise ride height adjustments via a continuous thread on the galvanized strut.
  • Rebound Damping Adjustment: Fine-tune your suspension for comfort or sportiness with 16 distinct clicks of rebound adjustment.
  • KW Engineering: Built using KW’s advanced twin-tube damping technology for superior performance and durability.
  • Corrosion-Resistant Construction: Galvanized steel struts with multi-layered sealing protect against dirt and weather conditions.
  • TÜV Approved: Meets stringent safety and quality standards.
  • Complete Solution: Includes adjustable spring plates, race spring system, bump stops, and dust protection.
