Key Features
Fits Audi A4 17-25, S4 18-25, RS4, A5 17-25, S5 18-25, RS5 18-25
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!
Fits Audi A4 17-25, S4 18-25, RS4, A5 17-25, S5 18-25, RS5 18-25
