034Motorsport's B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5, Allroad 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.
