The MMR Performance rear brake upgrade for the F56 MINI uses a pair of 325mm fully-floating discs, supplied with a billet steel bracket to re-locate the OE rear caliper. Our rear kit provides a balanced braking setup when upgrading to a more efficient front braking solution. Finished with our proprietary grooved disc design, which not only offers a visual boost and matches either of our 6-piston front brake upgrade kits, it also helps to ensure a glaze-free pad surface, giving you optimum braking performance even under extreme temperatures and usage.
