New ECS Tuning Tunnel Brace for your Audi B9 A4/S4
Incremental upgrades make a difference, especially when you plan ahead. If you are strengthening the chassis of your B9 A4 or S4, all the help you can get makes a big difference when everything is complete. The factory transmission tunnel brace is basically cosmetic and not ideal for improving the stiffness of your chassis. Our new Billet Transmission Tunnel Brace is a solid aluminum replacement that offers sturdier construction (and better looks) to help add strength to your Audi.
