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

This Brembo GT Big Brake Kit for the rear of your 2015-2018 BMW M3 (with CC Brake Equipment) includes everything you need to significantly upgrade your stopping power. You get a pair of 4-piston calipers, two 380x28mm two-piece rotors with a Type 3 slotting pattern, caliper mounting brackets, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake components with a more robust and performance-oriented setup.

The calipers are cast aluminum, which helps keep weight down while maintaining strength. They house four pistons, allowing for more even pressure distribution across the brake pad surface, which translates to better pedal feel and more consistent braking. The two-piece rotors are a notable feature; the cast iron friction ring is attached to an aluminum hat. This design helps manage heat more effectively and can reduce rotational mass compared to a one-piece rotor. The Type 3 slotting pattern on the rotors is designed to help sweep away dust and gas that can build up between the pad and rotor, ensuring a cleaner contact surface and improved braking performance, especially during repeated hard stops. This setup is a substantial upgrade for drivers who demand more from their braking system.

When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. While this kit is designed as a direct replacement for the factory components it upgrades, ensuring proper installation is key to realizing its full performance potential. This Brembo kit is a popular choice for M3 owners looking to enhance their vehicle's track capability or simply achieve a more confident and powerful braking experience on the street.
