MMX 2-Piece Front Brake Discs/Rotors – MINI JCW F55 F56 F57
Upgrade your Gen 3 MINI JCW (F55, F56, F57) with MMX’s premium 2-piece 335mm front brake discs/rotors.

Perfect for spirited road driving or dedicated track use, the MMX brake system is the ultimate performance upgrade for your MINI.
Performance Benefits
Improved Cooling: Runs up to 30% cooler than OEM with 48 curved cooling vanes, enhancing airflow and reducing fade.
Two-Piece Floating Design: 335mm x 30mm discs expand radially and axially under heat to help prevent warping and cracking common in single-piece discs.
Extended Lifespan: Proprietary alloy friction surface and floating bobbin system support durability under extreme braking conditions.

Lightweight Construction: Aerospace grade 6061-T6 aluminum center hats reduce unsprung weight for sharper handling and improved performance.
