APR Strut Tower Brace (B9) - Audi A4 / S4 / RS4 / A5 / S5 / RS5 (2017-2025) - APR (SUS00027)
(sus00027)
Introducing the APR Strut Tower Brace (B9 Chassis - A4/5, S4/5, & RS4/5)
The APR Strut Tower Brace for the B9 Chassis A4/5, S4/5, RS4/5, is engineered to enhance chassis rigidity, reduce flex, and improve handling for a more connected driving experience. While many systems prioritize the visual aesthetics of the engine bay, ours is a true performance upgrade designed for real-world handling improvements.
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.
True to our motto of Performance Without Compromise, this system provides a stiffer front end without introducing unwanted noise, vibration, or harshness (NVH).
The APR B9 Strut Tower Brace is the ultimate solution for drivers seeking sharper handling, reduced chassis flex, and a more responsive driving experience—all without sacrificing daily drivability!
Features:
- Increased Chassis Rigidity – Reduces flex under load for improved suspension performance and handling stability.
- 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.
- Full Strut Tower Integration – Connects both towers and the firewall for superior structural reinforcement.
- Adjustable Preload with Turnbuckle – Fine-tune chassis stiffness to optimize handling for different driving conditions.
- Improved Steering Feel – Enhances driver feedback and consistency during aggressive driving.
- No Compromise on Comfort – Engineered to prevent additional NVH, maintaining a smooth and refined ride.
- Direct Bolt-On Installation – No cutting or permanent modifications required, making installation seamless.
- 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.
