APR 18-25 Audi A4 Quattro/A5 Quattro/RS5/S4/S5 (B9) Strut Brace Tower

By replacing the factory-stamped aluminum brace with a high-strength tubular chromium-molybdenum alloy steel system, we significantly increase structural support while maintaining ride comfort. Additionally, our cross-brace design links both strut towers, and an integrated turnbuckle allows for precise preload adjustments, further reinforcing the chassis under heavy cornering and acceleration.

• High-Strength Tubular Cr-Mo Alloy Steel Construction –  Stronger than the factory-stamped aluminum brace for maximum strength and durability, featuring a black powder-coated finish for superior corrosion resistance and lasting performance.
• High-Quality Materials – Constructed from durable 25mm OD / 19mm ID high-strength tubular chromium-molybdenum alloy steel with billet end caps, TIG welding, black powder coating, and all stainless steel hardware.
• Adjustable Preload with Turnbuckle – Fine-tune chassis stiffness to optimize handling for different driving conditions.
• Increased Chassis Rigidity – Reduces flex under load for improved suspension performance and handling stability.
• Direct Bolt-On Installation – No cutting or permanent modifications required, making installation seamless.
• Full Strut Tower Integration – Connects both towers and the firewall for superior structural reinforcement.
• No Compromise on Comfort – Engineered to prevent additional NVH, maintaining a smooth and refined ride.
• Improved Steering Feel – Enhances driver feedback and consistency during aggressive driving.
