Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Slotted Type1-Red

This Brembo Rear GT Big Brake Kit includes everything you need to upgrade the braking performance on your 2015-2018 BMW M3 (excluding models with CCB - Carbon Ceramic Brakes). You'll get a pair of red 4-piston cast aluminum calipers, two 345x28mm two-piece rotors with a Type 1 slotting pattern, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake setup with a more robust system, offering a significant improvement in stopping capability.

The calipers are crafted from cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Inside, the 4-piston design distributes braking force more evenly across the pad surface, leading to better heat management and more consistent pedal feel, especially during repeated hard stops. The two-piece rotor construction, with a cast iron friction ring and an aluminum hat, further reduces weight and allows for better thermal expansion without warping. The Type 1 slotting pattern on the rotors is specifically designed to help sweep away dust and gas that can build up between the pad and rotor, maintaining optimal contact and preventing fade.

Upgrading to a big brake kit like this is a substantial change that can make a noticeable difference in how your M3 handles spirited driving or track use. While this kit is designed as a direct replacement for the factory components, it's always a good idea to consult the manufacturer's installation guide for specific torque values and any required tools. Ensure your vehicle is not equipped with the factory Carbon Ceramic Brakes, as this kit is not compatible with that system.
