MMX Underbody Chassis Brace | BMW | M2 | M3 | M4 | F8x

The MMX Underbody Chassis Brace is a direct replacement for the factory brace on BMW F8x M2, M3 and M4 models, engineered to provide an additional 15mm of exhaust clearance whilst maintaining original ground clearance. Precision machined from billet 6061-T6 aluminium, it also adds chassis stiffness for improved dynamic performance, with no modifications required for installation.

Clearance Without Compromise.

The MMX Underbody Chassis Brace has been developed specifically for the BMW F8x M2, M3 and M4 platform, providing an additional 15mm of exhaust clearance over the factory brace. This increased clearance helps accommodate larger diameter aftermarket exhaust systems, reducing the risk of contact whilst maintaining the original ground clearance.

Beyond providing additional clearance, the MMX Underbody Chassis Brace also contributes to increased chassis rigidity, helping to improve overall dynamic performance. By reinforcing a key structural area beneath the vehicle, the brace aids stability and responsiveness, making it a worthwhile upgrade whether on the road or track.

Precision CNC machined from billet 6061-T6 aluminium, the brace combines exceptional strength with low weight. Its carefully optimised profile removes a considerable amount of unnecessary material whilst retaining the rigidity required for demanding use, delivering the premium finish and engineering expected from every MMX product.
