Improve Handling on your B9 Chassis A4/5, S4/5, RS4/5!
By: APR | 2025-03-26The 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!
