MMX Performance 3-Piece Complete Underbody Chassis Brace Set - Mini Cooper S & JCW (F5x; Incl. GP) 2014-2024 / Clubman (F54) 2020-2024
Lease for as low as $/week
The MMX Performance MINI F5X 3-Piece Complete Underbody Chassis Brace Set is the flagship chassis-stiffening upgrade for the F5X-generation MINI. Where the F56 and its siblings use three pressed-steel underbody braces from the factory, this kit replaces all three at once with billet T6061 aluminum equivalents, cutting weight, adding rigidity, and giving you a finished, hardware-included installation in a single box.
Each brace is CNC-machined from 6061-T6 billet aluminum and finished in gloss black anodizing for long-term corrosion resistance. The center brace is shaped to add valuable exhaust clearance, which becomes important on lowered cars or cars running an aftermarket exhaust system. All three pieces install in their original factory locations using the supplied hardware, no cutting, no welding, no permanent modification.
The benefit on the road is immediate: tighter chassis response under cornering load, less perceived flex through transitions, and a more deliberate feel through the steering. The MINI F5X is already one of the most engaging hot hatches on the market, and the MMX 3-piece brace set sharpens up exactly the area where the factory chassis goes a little soft.
Whether your MINI is daily-driven, tracked, or somewhere in between, fitting all three braces together is the strongest single chassis upgrade you can make to the F5X platform, and the cleanest, since each piece has been engineered as part of a coordinated set.
