Brembo 15-18 M3 (CC Brake Eqpt) Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type1-Black

If you're looking to significantly improve your 2015-2018 BMW M3's braking performance, especially when equipped with the Competition Package, this Brembo Rear GT Big Brake Kit is a serious consideration. This kit replaces your factory rear brakes with a much larger and more robust system designed for demanding use. It features substantial 380x28mm two-piece rotors and powerful four-piston calipers, built to handle the heat and stress of spirited driving and track days.

The heart of this kit is Brembo's renowned engineering. The calipers are cast aluminum, keeping weight down while maintaining strength. They house four pistons, which distribute clamping force evenly across the larger, slotted rotors. These two-piece rotors are a notable upgrade; the floating design allows the rotor to expand and contract with heat without inducing stress or warping, and the Type 1 slots help sweep away dust and gas, keeping the pad surface clean for consistent stopping power. The black finish on the calipers and the slotted rotor design give your M3 a distinct, performance-oriented look behind the wheels.

This kit is designed as a comprehensive rear brake upgrade. It includes everything needed to replace your stock rear braking components with this high-performance setup, ensuring a direct fit for the specified M3 models with Competition Package brakes. When undertaking a brake upgrade of this magnitude, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications to ensure proper setup.
