Brembo 15-18 M3 Excl CC Brakes Rr GT BBK 4Pis Cast 380x28 2pc Rotor Drilled-Yellow

This is the Brembo Rear GT Big Brake Kit, part number 2S1.9013A5, designed for the 2015-2018 BMW M3 models that do not have the Carbon Ceramic (CC) option. This kit is a substantial upgrade for your M3's braking system, focusing on enhanced stopping power and heat management for spirited driving and track use. It includes everything you need to replace your factory rear brakes with a high-performance setup from a well-known name in braking technology.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over stock. These calipers grip a pair of 380x28mm two-piece rotors. The rotors are drilled, which helps to dissipate heat and gasses, improving braking consistency, especially under heavy use. The two-piece design allows for better thermal management as the aluminum hat can shed heat more effectively than a solid one-piece rotor. This setup is built to handle the demands of performance driving, offering improved fade resistance and a more direct pedal feel.

When installing this kit, you'll be replacing your entire rear brake assembly. The kit comes with the calipers, rotors, and likely the necessary mounting hardware and brake lines to ensure a proper fit. It's important to ensure your vehicle does not have the factory Carbon Ceramic brakes, as this kit is specifically designed for the standard iron rotor setup. Proper bedding-in of the new pads and rotors is crucial to achieve optimal performance and longevity from this high-performance brake system.
