Underbody Chassis Brace – Centre | MINI F56 F55 F54
Upgrade the handling, rigidity and exhaust clearance of your MINI with this Centre Underbody Chassis Brace for MINI F56, F55 and F54. Precision machined from lightweight billet T‑6061 aluminium and finished in gloss black anodising, this MMR centre tunnel brace replaces the standard steel OE brace to deliver a stronger, lighter and better looking solution for road and track driving.
If you run a larger diameter aftermarket exhaust system, the OE brace can limit clearance. This centre underbody brace has been designed to provide the extra space you need while maintaining crucial body stiffness. Enjoy sharper steering response and improved chassis stability without adding noise, vibration or harshness to the cabin. It is a simple, fully reversible bolt-on upgrade that uses the factory mounting points and requires no drilling or trimming.
