034Motorsport's X-Brace Chassis/Subframe Reinforcement has arrived for RHD (right-hand drive) B8.5 Audi A4/S4/RS4, A5/S5/RS5, and Q5/SQ5 models. This robust billet aluminum brace replaces the original lower subframe brace to increase torsional rigidity, resulting in improved handling characteristics and enhanced steering precision. The 034Motorsport X-Brace was engineered and tested to outperform the factory’s welded, stamped steel part and ensure your vehicle's suspension geometry is not compromised by chassis flex under hard cornering.
The X-Brace is a bolt-in upgrade for the factory part on B8.5 chassis (facelift) vehicles and offers direct and responsive handling performance without sacrificing comfort.
The factory Audi 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.
The 034Motorsport X-Brace is a one-piece billet aluminum lower subframe brace which replaces the factory front subframe brace to increase torsional rigidity, resulting in improved steering feel and handling performance. Machined in-house from a single piece of 1.25” (3.175 cm) thick 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. Weighing in at 9.1 pounds versus 8.5 pounds for the factory stamped steel part, the X-Brace adds significant strength and rigidity with a negligible effect on weight.
This chassis brace upgrade was thoroughly tested by 034Motorsport dealers and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.
