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

Brembo is a name synonymous with high-performance braking systems, and this Rear GT Big Brake Kit (BBK) continues that legacy. This kit is designed for the discerning owner of a 2015-2018 BMW M3 (excluding models with CCB - Carbon Ceramic Brakes), offering a significant upgrade over the factory setup. It’s built to enhance stopping power and heat management, crucial for spirited driving and track use.

At the heart of this kit are the 4-piston calipers, forged from cast aluminum for a strong yet lightweight housing. These calipers grip the substantial 345x28mm two-piece rotors, which feature a slotted design. The slots help to sweep away dust and gas that can build up between the pad and rotor surface, maintaining consistent friction and preventing glazing. This particular kit uses Brembo's Type 3 slots, known for their effectiveness in clearing debris and dissipating heat. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat independently from the iron braking surface, reducing the risk of rotor warping.

When you're looking to improve your M3's braking performance, especially if you plan on more demanding driving scenarios, a big brake kit like this from Brembo is a solid choice. It’s a comprehensive package that addresses key areas of braking performance: caliper clamping force, rotor thermal capacity, and pad-to-rotor interface. This kit is a significant investment in your vehicle's safety and performance, providing a more confident and capable braking experience.
