034Motorsport's B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5, Allroad, & 95B Porsche Macan X-Brace Chassis Reinforcement Upgrade is designed to replace the factory front subframe brace to increase torsional rigidity, resulting in improved steering feel and handling performance. Machined in-house from T6-6061 billet aluminum, the 034Motorsport X-Brace is engineered to outperform the stock welded, stamped steel part and ensure that suspension geometry is not compromised by chassis flex under hard cornering.
The beautifully-crafted X-Brace is a direct, bolt-in upgrade for both B8 and B8.5 chassis vehicles, and offers more direct and consistent steering feel, and better handling, without sacrificing comfort.

034Motorsport is proud to offer our Billet Aluminum X-Brace Chassis Reinforcement Upgrade for the B8 & B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5, Allroad, and 95B Porsche Macan! The factory Audi/Porsche front subframe brace is manufactured from multiple pieces of stamped steel, and allows for performance-hindering chassis flex under load. This torsional flex can result in improper suspension geometry and alignment when cornering, and leads to vague steering feel and lack of steering precision.
