Brembo 15-18 M3 (CC Brake Eqpt) Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type3-Red

If you're looking to significantly step up the braking performance on your 2015-2018 BMW M3 equipped with the Competition Package, this Brembo Rear GT Big Brake Kit is a serious consideration. This kit replaces your factory rear braking components with a much larger and more capable setup, designed to handle the demands of spirited driving and track use. It features substantial 380x28mm two-piece rotors and robust four-piston calipers, all from a brand known for its high-performance braking systems.

The heart of this kit lies in its substantial hardware. The calipers are cast aluminum, keeping weight down while offering a solid foundation for the pistons. These calipers clamp down on large 380x28mm two-piece rotors. The two-piece design allows the rotor and hat to expand and contract independently, which helps reduce the risk of rotor warping under heavy thermal loads. The rotors themselves are slotted with Brembo's Type 3 pattern, which helps to sweep away dust and gas that can build up between the pad and rotor surface, ensuring consistent stopping power even during prolonged braking events. The calipers come finished in a striking red, adding a visual upgrade to match the performance gains.

This kit is designed as a direct replacement for the factory rear brakes on the specified M3 models with the Competition Package. It includes everything needed to upgrade the rear braking system, providing a noticeable improvement in stopping distance and fade resistance. When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide to ensure all components are torqued to spec and properly seated. This Brembo kit represents a significant investment in your vehicle's performance and safety, offering a well-built solution for those who push their M3 to its limits.
