MMR Performance Rear Braking Package for Mini F56, F55, F54 - 325 mm Two-Piece Floating Slotted Rotors

Unlock serious rear-end stopping confidence on road and track with the MMR Performance rear braking package for the latest Mini platforms. This conversion uses larger 325 mm two-piece floating slotted rotors in FC-25 carbon steel with precision billet steel relocation carriers to position the factory rear calipers further outboard for increased leverage and stronger braking torque. Expect a firmer pedal, repeatable performance under heat, cleaner pad faces and impressive stability during hard deceleration.

Key reasons Mini drivers choose this upgrade

• 325 mm two-piece floating rotors in FC-25 carbon steel for superb heat control and durability during repeated heavy use
• Billet steel caliper relocation carriers move the OE caliper outward for a clear mechanical advantage and increased braking torque
• Slotted groove pattern helps keep pads deglazed for consistent bite and dependable modulation on fast road and trackdays
• Floating rotor-to-hat mounting allows thermal expansion and contraction to help reduce the risk of cracking
• Retains standard rear calipers and the factory handbrake for OEM reliability and straightforward servicing
• Open pad choice so you can run your preferred compound for daily driving, spirited B-road use or circuit work
• Complements a quality front big brake kit to deliver balanced, confidence-inspiring deceleration
