| Description_MKT | Introducing the APR Strut Tower Brace (B9 Chassis - A4/5, S4/5, & RS4/5) |
| Description_MKT | 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. |
| Description_MKT | 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. |
| Description_MKT | True to our motto of Performance Without Compromise, this system provides a stiffer front end without introducing unwanted noise, vibration, or harshness (NVH). |
| Description_MKT | 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! |
| Description_FAB | Increased Chassis Rigidity – Reduces flex under load for improved suspension performance and handling stability. |
| Description_FAB | 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. |
| Description_FAB | Full Strut Tower Integration – Connects both towers and the firewall for superior structural reinforcement. |
| Description_FAB | Adjustable Preload with Turnbuckle – Fine-tune chassis stiffness to optimize handling for different driving conditions. |
| Description_FAB | Improved Steering Feel – Enhances driver feedback and consistency during aggressive driving. |
| Description_FAB | No Compromise on Comfort – Engineered to prevent additional NVH, maintaining a smooth and refined ride. |
| Description_FAB | Direct Bolt-On Installation – No cutting or permanent modifications required, making installation seamless. |
| Description_FAB | 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. |
