MMX Rear Brake Rotor Upgrade for F56 Mini Cooper | MMR21-1401R

Take your F56 Mini Cooper JCW braking performance to the next level with the MMX Performance Rear Brake Rotor Upgrade (MMR21-1401R). This upgrade features a pair of 325mm, FC-25 carbon steel two-piece fully-floating discs, engineered to deliver exceptional stopping power even under extreme temperatures. Supplied with billet steel brackets, the kit repositions the OE rear caliper further outboard for optimized braking leverage and performance.

Balanced Braking for High-Performance Applications

For a complete performance braking solution, the MMX Rear Brake Upgrade is the ideal complement to an upgraded front braking setup, such as our MMX Front Big Brake Kit. This balanced setup enhances both braking efficiency and aesthetics, with a matching visual appeal through your Mini’s alloys. Retaining the factory calipers, this upgrade relocates them to a position that maximizes mechanical advantage, ensuring rear braking force that complements the enhanced front setup.

Key Features of the MMX Rear Brake Rotor Upgrade:

• 325mm FC-25 Carbon Steel Discs: High-grade, fully-floating discs designed for optimal heat dissipation and durability.
• Billet Steel Brackets: Reposition the OE rear caliper to align with the larger disc diameter for improved braking force.
• Proprietary Groove Design: Reduces brake pad glazing and ensures optimal pad-to-disc contact, even in high-stress conditions.
• Thermal Expansion Control: Fully floating mount allows for thermal expansion, preventing disc cracking and prolonging life.

Ideal Setup and Compatibility

This rear brake upgrade retains the factory rear calipers, preserving the handbrake function and allowing for a wide selection of brake pads. However, it’s essential to pair this upgrade with a quality front Big Brake Kit to maintain optimal front/rear brake bias.
