09D CNC-Machined Aluminium Tunnel Brace – Strength, Clearance & Precision EngineeringOur 09D Tunnel Brace is a CNC-machined aluminium reinforcement component designed to enhance the structural rigidity of the vehicle’s exhaust tunnel area while also offering increased clearance for large-bore performance exhaust systems. Installed on the underside of the vehicle, this brace forms part of the floor pan structure, helping to reduce chassis flex and improve overall stability—particularly important on fast road and performance builds. Each brace is individually machined in-house from T6-6082 aluminium, a material known for its excellent strength-to-weight ratio and corrosion resistance. To further protect the part and elevate its appearance, we finish every brace with a durable anodised coating, sealing the surface from the elements while adding a clean, professional look.Key Features & Benefits:• Improved Structural Rigidity – Reinforces the factory tunnel section, reducing flex and improving underbody stability.•  Designed for Performance Exhausts – Profiled to provide additional clearance for enlarged bore exhaust systems, reducing the risk of contact or vibration.• CNC-Machined In-House – Precision-machined from T6-6082 aluminium, ensuring a perfect fit, repeatable quality, and a high-strength final part.• Anodised Protective Finish – Enhances corrosion resistance and appearance, ideal for long-term durability in all driving conditions.• Lightweight but Strong – Offers all the strength needed without adding unnecessary weight.Engineered for Strength, Designed for ClearanceThe 09D Tunnel Brace is the result of carefully considered design and in-house machining expertise, providing a simple but effective upgrade that combines structural reinforcement with intelligent exhaust system accommodation. BRACE YOURSELF Functional underbody bracing never looked so good Designed and manufactured at our in-house machine shop in the U.K. the ZERONINE Design tunnel brace offers a functional upgraded brace option that also oozes our design DNA in the aesthetic department, too

Racingline Billet Underbody Tunnel Braces Want to sharpen up your MQB handling responses? MQB Billet Underbody Tunnel Braces mount under the body to help fight body flex. This improves rigidity to help refine the handling, whilst also providing valuable extra clearance for larger diameter exhaust system. What do they do? MQB cars rely on thin stamped-steel OE tunnel braces underneath in an attempt to reinforce the body’s weaker points and limit chassis flex under demanding loads. Our new Billet Underbody Braces replace these weak braces with intricately machined aluminium replacements, greatly improving stiffness, giving much better exhaust clearance and even look great! CNC Machined from a solid billet of 6061-T6 Aluminium, each brace has been engineered to remove unnecessary material whilst still increasing rigidity. With any 3″ diameter exhaust system, the OE brace gives insufficient clearance. So rather than removing the tunnel brace, our new Rear Tunnel Brace at last gives you the option to replace it, giving you the clearance you need plus maintaining crucial body stiffness. Despite adding stiffness, this improved dynamic performance comes without sacrificing any ride quality or introducing any additional noise, vibration, or harshness into the cabin. The brace designs mean that installation is simple, using existing body mounting points with no drilling or trim removal required, ensuring fitment is completely reversible. We offer two braces – a Centre and a Rear Tunnel Brace. Owners of FWD cars can fit both, AWD cars can only fit the Rear Tunnel Brace. Looking to fit a larger bore Exhaust System? For large diameter aftermarket exhausts, there simply isn’t clearance space above the factory tunnel brace. Many owners have no choice but to remove the brace. But the brace is there for a reason. With the extra clearance our Rear Tunnel Brace gives, you can now maintain strength and fit your bigger exhaust. VWR810005 – Rear Tunnel BraceVWR810004 – Centre Tunnel Brace (Front-wheel drive only)
