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.

Features:
  • T6-6061 Billet Aluminum Construction
  • CNC-Machined In-House
  • Clear Anodized Finish for Durability
  • Engineered to Replace Factory Front Subframe Brace
  • Drastically Reduces Chassis Flex When Cornering
  • Enhances Handling Dynamics and Performance
  • Improves Steering Feel, Consistency, and Precision

Lid on one did not work/grind salt or pepper
I received 2 of these products . One is good. The other lid was not good to grind. I had to purchase from a different seller and take the lid off that one to exchange for the lid that would not grind. Nothing would come out no matter how much I tried adjusting the lid. So I was actually out of money for having to reorder another salt/pepper grinder. The one that worked I give 5 stars the one that didn’t I wish I could get a refund on but it’s probably too late to receive a refund. I didn’t try it out until it was too late for a refund.
