MMX Rear 325mm Brake Upgrade - MINI Cooper S F56 JCW

Take your Gen 3 MINI F55, F56, or F57 JCW to the next level with our premium rear 2-piece brake discs/rotors—a direct bolt-on upgrade for your OE units. Designed for extreme heat resistance, reduced weight, and superior stopping power, they enhance braking performance for both road and track use.Supplied with rear caliper carrier matched in the JCW red colour — a true plug-and-play solution.

Our 325mm discs/rotors run up to 30% cooler than OE, and increase cooling efficiency by up to 30%.

Utilising a much larger two-piece 325mm x 10mm floating design allows our disc and hat to expand radially and axially as they absorb heat generated from hard use, avoiding the most common cause of warping and cracking seen in single-piece discs.

Our rear kit includes a dedicated carrier bracket using the OE mounting hardware rather than a simple spacer to ensure superior alignment, strength, and performance. While a spacer may serve as a basic fitment solution, it lacks the structural integrity and precision of a properly engineered bracket.

Due to the efficiency of this design, MMX discs/rotors last considerably longer than factory discs. The friction surface features our trademark groves that increase bite and remove debris from the pad surface giving the perfect balance between brake feel and longevity.

The centre hat is crafted from 6061-T6 aircraft specification aluminium. Our grooved discs/rotors are constructed from proprietary metal alloys, that can withstand immense braking temperatures while holding form.

As the MMX discs/rotors dissipate heat much more efficiently, the factory pad compound works much better in real-world conditions; only when you’re using the vehicle on the track would we recommend considering a different pad altogether. But rest assured, you can use OEM or after-market performance pads with our discs.
