MMX 2-Piece 325mm x 10mm Rear Brake Discs/Rotors – MINI JCW F55 F56 F57
Take your Gen 3 MINI JCW (F55, F56, F57) to the next level with MMX’s premium rear 2-piece 325mm brake discs/rotors. Designed as a direct bolt-on upgrade for OEM units, this kit delivers superior heat resistance, reduced weight, and consistent stopping power. Supplied with a rear caliper carrier matched in JCW red, this is a true plug-and-play performance solution for both road and track use.
Performance Benefits
Improved Cooling: Runs up to 30% cooler than OEM discs, enhancing airflow and reducing fade.
Two-Piece Floating Design: 325mm x 10mm discs expand radially and axially under heat, helping to prevent warping and cracking seen in single-piece discs.
Precision Carrier Bracket: Dedicated bracket uses OE mounting hardware for superior alignment, strength, and safety compared to simple spacer solutions.
Extended Lifespan: Proprietary alloy friction surface and floating bobbin system ensure durability under demanding conditions.
Enhanced Braking Feel: Trademark grooved surface improves pad bite, clears debris, and balances brake feel with longevity.
Lightweight Construction: Aerospace grade 6061-T6 aluminum center hats reduce unsprung weight for sharper handling.
