MMX 2-Piece 335mm x 30mm front discs/rotors for MINI F56 JCW Take your Gen 3 MINI F55, F56, or F57 JCW to the next level with our premium front 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. Our 335mm discs/rotors run up to 30% cooler than OE, and increase cooling efficiency by up to 30%. F-Series JC Ws come with a fairly substantial 4-pot calipers straight from the factory. Whilst the stock caliper works well, the same can’t be said for the discs. The factory 335mm discs may look the part but soon show their flaws with some spirted or on-track driving. Utilising a two-piece 335mm x 30mm 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. 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. The discs also utilise 48 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat. Internal vanes are used to draw air through the centre of the disc outward, allowing the heat to transfer as it passes. The rotation of the discs and vanes play an important role in brake cooling as it acts as a pump to move air and unlike the OEM brake discs, our disc/rotor upgrade consists of a right and left-hand disc to optimise cooling and ensure consistent stopping power for your vehicle. 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. Features 335mm x 30mm. Fitment for OEM front JCW calipers. Flexible fitment for OEM or after-market pads.
