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

This Brembo Rear GT Big Brake Kit (BBK) includes everything you need to upgrade the braking performance on your 2015-2018 BMW M3 equipped with the CC Brake Equipment. You get a pair of four-piston calipers finished in a striking fluorescent yellow, two-piece 380x28mm slotted rotors, and all the necessary hardware for installation. This kit is designed to replace your factory rear brakes with a more robust and capable system, offering improved stopping power and heat management for spirited driving and track use.

The calipers are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Brembo's signature slotted rotors are included, featuring a Type 1 slot pattern. These slots help to vent gases and dust away from the pad surface, which means more consistent braking performance, especially under heavy use. The two-piece rotor design allows the friction ring to expand and contract independently of the hat, reducing the risk of rotor warping and improving thermal management. This combination of advanced caliper design and high-performance rotor technology is what makes Brembo a popular choice for serious braking upgrades.

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, ensuring proper installation is key to achieving the full benefit of the upgrade and maintaining safety. You'll notice a significant difference in pedal feel and fade resistance, especially during demanding driving conditions.
