Brembo 15-18 M3 Excl CC Brakes Rr GTR BBK 4Pis Billet 380x28 2pc Rotor Drilled-Nickel

Brembo is a name many performance enthusiasts trust for braking systems, and this GTR Big Brake Kit for the rear of your 2015-2018 M3 (excluding CC models) is a prime example of their work. This kit is designed to give your M3 a significant upgrade in stopping power and heat management, crucial for spirited driving or track use. It replaces your factory rear brakes with a robust, high-performance setup that can handle more demanding conditions.

At the heart of this kit are the billet aluminum, 4-piston GTR calipers, known for their strength and light weight. These calipers grip 380x28mm two-piece rotors. The rotors themselves are drilled, which helps to dissipate heat and gasses, improving consistent braking performance, especially under heavy use. The two-piece design allows for better thermal management and can make rotor replacement simpler down the line. The nickel finish on the rotors adds a layer of corrosion resistance, helping to keep them looking good even in varied weather conditions.

This is a comprehensive rear brake kit, intended to provide a substantial improvement over stock. When installing a big brake kit like this, it's always a good idea to consult the manufacturer's installation guide to ensure all components are fitted correctly for optimal performance and safety. While this kit focuses on the rear, consider how your front brakes will complement this upgrade for balanced stopping power.
