Product Details

​The ECS Tuning Billet Tunnel Brace, for the Audi B8 chassis, replaces the flimsy and thin stamped brace installed from the factory. The substantial added thickness and width ensure a more rigid connection to both sides of the tunnel. The chassis brace is CNC machined out of 6061-T6 billet aluminum and beautifully anodized in your choice of gloss red or gloss black to offer both great looks and durability.

Our ECS Tunnel Brace was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We ensure that the highest level of precision and quality is delivered throughout rigorous long term product testing and cutting edge product development methods.

Installation is simple. The brace mounts in the factory location and re-uses the OEM hardware. Take a look at the installation PDF below for proper torque specs!
