Brembo 15-18 M3 (CC Brake Equipped) Front GT BBK 6 Piston Cast 405x34 2pc Rotor Slotted Type1-Black

This Brembo GT Big Brake Kit for the 2015-2018 BMW M3 (equipped with CC Brakes) includes everything you need to significantly upgrade your front braking system. You get a pair of massive 405x34mm two-piece slotted rotors, a set of six-piston forged aluminum calipers finished in black, and all the necessary mounting hardware and brake lines to complete the installation. This kit is designed to give your M3 a serious boost in stopping performance, especially under demanding conditions.

Brembo is well-known for its high-performance braking components, and this GT kit is a prime example. The calipers are forged for strength and then cast, offering a solid foundation for braking power. The two-piece rotors feature a floating design, which helps manage heat expansion and reduces the risk of rotor warping. The slots on the rotor surface are there to help clear away brake dust and gases, ensuring consistent contact between the pad and rotor for improved braking feel and performance, particularly during repeated hard stops. The larger rotor surface area and the six-piston caliper design work together to distribute braking force more effectively, leading to shorter stopping distances and better heat dissipation than stock brakes.

Upgrading to a big brake kit like this is a substantial modification, and it's often done by owners looking for the best possible braking performance for track days or spirited driving. Because this is a complete kit, it aims to be a direct replacement for your factory setup, though it's always a good idea to consult the manufacturer's installation guide for specific details and any additional components you might need, such as specific brake fluid.
