Racingline underbody tunnel brace, VAQ MQB All-wheel drive models

The MQB platform vehicles come equipped with thin stamped-steel OE tunnel braces, designed to add some reinforcement to the body’s weaker points and reduce chassis flex. However, under demanding loads, these factory braces can fall short.

The new Racingline Billet Underbody Braces are precision-engineered aluminium replacements that significantly improve chassis stiffness, offer better exhaust clearance, and even add a stylish touch. Each brace is CNC machined from a solid billet of 6061-T6 aluminium, carefully crafted to remove unnecessary material while maximizing rigidity.

For any 3” diameter exhaust system, the OE brace often provides inadequate clearance. The Racingline Rear Tunnel Brace solves this issue, allowing you to retain essential body stiffness while gaining the needed clearance. Now, instead of removing the brace, you can install this high-quality upgrade.

Despite the added rigidity, these braces enhance dynamic performance without affecting ride comfort or introducing additional noise, vibration, or harshness into the cabin.

Installation is simple, utilizing existing body mounting points with no drilling or trim removal required, making fitment fully reversible.

We offer two braces – a Centre Brace and a Rear Tunnel Brace. Owners of FWD models can fit both, while AWD models are compatible with the Rear Tunnel Brace only.
