034 Motorsport X-Brace Billet Aluminum Chassis Reinforcement, B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5, Allroad
Tax excluded. Shipping calculated at checkout
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, and Allroad! 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 billet aluminum chassis reinforcement 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. Weighing in at 8.2 pounds versus 7.8 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 and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.

What Is Your Order & Shipping Policy?
It is your responsibility to provide accurate shipping information at checkout. T1 Motorsports is not liable for any delays, lost shipments, or additional costs resulting from incorrect or incomplete addresses submitted during ordering.
What Is Your Return & Exchange Policy?
All processed orders that have not shipped will incur a 6% processing fee, this is mainly to cover any payment processing and cancelation fee with the manufacturer or warehouse. A processed order is an order that has already been put in our system and the product has been taken out of inventory and moving towards the packing and shipping face.
On special order or custom-made orders, the processing face is indicated when the manufacturer has received our order. Please be courteous and notify us ASAP if you wish to cancel any order(s) that were recently placed in order to prevent it from shipping out.
Due to the nature of racing and performance vehicles, no returns will be accepted on special order items, opened, installed, incomplete, or otherwise used products. If a product is ordered and not wanted, the UNUSED item can be returned within 30 days after the product has been delivered. This does not apply to SPECIAL ORDER items. Once the product is returned, you have two options for your refund:
You may have your purchase refunded back on your original payment method minus a 20% restocking fee of the total amount. In this case, please know that the initial shipping is not refundable (free shipping items still incur shipping chargers which MUST be deducted on a return). All items wanting to be returned MUST be reported within 30 days of delivery date. If you are still browsing and want an alternate product, we can provide you with a full credit minus shipping costs as a T1 Motorsports store credit. Some brands are excluded and may incur up to a 10% restocking fee. Please contact us to confirm.
On both refund options, a return shipping label may be provided if you are unable to ship the product(s) back using your own method of shipping. This shipping cost will be deducted from your total refund or credit.
