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

This Brembo Rear GT Big Brake Kit (BBK) is a comprehensive upgrade for your 2015-2018 BMW M3 equipped with the CC Brake Equipment. What you get in this kit are the essential components to significantly enhance your rear braking performance: a pair of four-piston "GT" calipers, two-piece 380x28mm rotors that are drilled for improved heat dissipation, and all the necessary hardware to get them installed. This isn't just a minor tweak; it's a substantial upgrade designed for drivers who demand more from their braking system, especially during spirited driving or track use.

The calipers in this kit are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. Brembo's reputation is built on performance, and these calipers are designed to work seamlessly with the included two-piece rotors. The 380x28mm rotor size offers a larger surface area for braking, and the drilled pattern helps vent gases and heat away from the pad surface, which can prevent brake fade under heavy use. The two-piece design allows for better thermal management between the rotor hat and the friction ring, reducing the risk of warping.

Installing a big brake kit like this is a significant undertaking, and it's important to ensure you have the right tools and knowledge, or to have a professional mechanic handle the job. This kit is a major investment in your vehicle's performance and safety, offering improved stopping power and consistency when you need it most. It's a well-built system from a trusted name in braking technology.
