Brembo 15-18 M3 Excl CC Brake Rr GT BBK 4Pis Cast 345x28 2pc Rotor Slotted Type3-Yellow

If you're looking to significantly improve the stopping power and heat management on your 2015-2018 BMW M3, this rear Big Brake Kit from Brembo is a serious consideration. This kit is designed to handle the demands of spirited driving and track use, offering a substantial upgrade over the factory braking system. It includes everything you need to replace your rear rotors and calipers with a high-performance setup that’s built to last.

At the heart of this kit are the 4-piston calipers, which offer more clamping force and better pad distribution than smaller calipers. These are paired with 345x28mm two-piece rotors. The two-piece design helps reduce weight and allows for better thermal management, as the rotor can expand and contract more freely. The rotors themselves are slotted, with Brembo's Type 3 slot pattern. These slots help to sweep away dust and gas that can build up between the pad and rotor surface, ensuring consistent braking performance even under heavy use. The cast iron construction of the caliper bodies ensures durability and heat dissipation.

This Brembo kit is a comprehensive solution for enhancing your M3's braking capabilities. While the installation is more involved than a simple pad and rotor swap, it's designed to fit your vehicle's specific mounting points. For optimal performance and safety, it's recommended to have this kit installed by a qualified technician who can ensure all components are properly seated and bled. This kit is a substantial investment in your vehicle's performance and safety, offering a noticeable difference in braking feel and fade resistance.
