Brembo 15-18 M3 Excl CC Brakes Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type1-Silver

This is the Brembo Rear GT Big Brake Kit for your 2015-2018 BMW M3. If you're looking to significantly upgrade your braking performance, especially for track days or spirited driving, this kit is a solid choice. It replaces your factory rear brakes with a much more robust setup designed to handle higher temperatures and provide more consistent stopping power under demanding conditions. The kit includes everything you need to get this advanced braking system installed on your M3.

At the heart of this kit are the Brembo 4-piston calipers, which offer increased clamping force over stock. These calipers are paired with 380x28mm two-piece rotors. The two-piece design helps manage heat more effectively, as the aluminum hat can dissipate heat away from the braking surface. The rotors themselves are slotted, which helps to clear out brake dust and gas that can build up between the pad and rotor, maintaining a cleaner contact patch for improved performance. The Type 1 slotting pattern is chosen for its balance of performance and noise reduction. The calipers come finished in a classic silver, complementing the look of performance wheels.

When installing a big brake kit like this, it's important to ensure you have the right tools and follow the manufacturer's instructions carefully. This kit is designed as a direct replacement for the factory rear brake components on the specified M3 models, meaning no major modifications should be necessary for installation. The improved thermal capacity and clamping force will make a noticeable difference in how your car stops, especially during repeated hard braking events.
