MMR Performance Rear Brake Upgrade for Mini F56, F55, F54 – 325 mm Two-Piece Fully Floating Rear Discs
Upgrade your Mini rear brakes with the MMR Performance Rear Brake Upgrade for Mini F56, F55 and F54. This rear brake kit transforms braking confidence on fast road and track, delivering stronger pedal feel and repeatable stopping power. The kit comprises a pair of 325 mm FC-25 carbon steel two-piece fully floating rear brake discs with billet steel brackets that relocate the factory rear caliper further outboard for a powerful mechanical advantage. Expect improved braking balance, better heat management and a clean, glaze-free pad surface thanks to the proprietary grooved disc design.
Ideal when paired with a quality front big brake kit, including the MMR front 6‑piston Big Brake Kit, this rear brake upgrade matches front and rear performance and looks superb through your alloys. It retains the factory rear calipers and the handbrake operation, and keeps your choice of rear brake pads open so you can select the compound that best suits road, fast road or track use.
Why choose this Mini rear brake upgrade
- 325 mm two-piece fully floating FC-25 carbon steel discs for outstanding heat control and durability
