ST XA Coilover Kit for 2018+ Audi A4/S4/A5 (B9) Sedan Quattro (Without Electronic Dampers)

At Eurozone Tuning, we are proud to offer premium suspension solutions tailored to enthusiasts. The ST XA Coilover Kit for the Audi A4, S4, and A5 (B9) Sedan Quattro is an excellent upgrade for drivers seeking precise ride height adjustment, enhanced handling, and customizable rebound damping. Developed with KW’s advanced damping technology, this kit delivers exceptional performance for both street and spirited driving.

Why Upgrade?

The factory suspension on the Audi B9 platform is designed for versatility but may lack the adjustability and sharp handling desired by enthusiasts. The ST XA Coilover Kit allows you to lower your vehicle’s center of gravity, reduce body roll, and fine-tune rebound damping for a sportier or more comfortable ride—all while maintaining everyday drivability.

Key Features:

  • Height Adjustable: Achieve the perfect stance with precise lowering adjustments:
    • Front Lowering: 0.8" - 1.8" (20mm - 45mm)
    • Rear Lowering: 0.8" - 1.8" (20mm - 45mm)
  • 16-Click Rebound Damping Adjustment: Fine-tune your suspension setup for comfort or sportiness with simple adjustments.
  • Composite Spring Perch: Made from friction-optimized polyamide composite material with a stainless steel insert to prevent corrosion and ensure long-lasting height adjustability.
  • Twin-Tube Technology: Reduces chassis vibrations and enhances driving dynamics by minimizing damping input reactions.
  • Galvanized Zinc-Coated Steel Struts: Provides excellent corrosion resistance for long-lasting performance.
  • TĂśV Approved: Meets stringent German safety and quality standards.
  • Complete Kit: Includes height adjustment tools, dust protection, bump stops, and a detailed damper setup manual.

Vehicle Fitment:

  • Make: Audi
  • Models:
    • Audi A4 (B9) Sedan Quattro (2018+)
    • Audi S4 (B9) Sedan Quattro (2018+)

  • Notes:

Bill's Take
ST coilovers are an excellent option for anyone looking to lower their car and improve handling without sacrificing ride comfort. They offer a perfect balance between everyday drivability and performance, all at a great price point. Plus, they’re highly adjustable, making it easy to dial in the perfect stance and feel for your car. Quick breakdown: X has no rebounding adjustment, XA has rebounding adjustment, and XTA has rebounding adjustment with more track geared valving.
