Brembo 08-13 M3 Rear GTS BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-3-Black HA

This Brembo Rear GTS Big Brake Kit (BBK) includes everything you need to significantly upgrade the braking performance on your 2008-2013 M3. You'll receive a pair of 380x28mm two-piece rotors featuring Brembo's Type-3 slotting pattern, designed to help dissipate heat and gasses. The kit also includes a set of four-piston cast iron calipers finished in black, along with all the necessary hardware for installation. This comprehensive package is built to enhance your vehicle's stopping power and heat management under demanding conditions.

The Type-3 slotting on these rotors is a notable feature, offering a more aggressive surface pattern than standard slots. This design helps to keep the rotor surface clean and provides a consistent bite for the brake pads, which is crucial for maintaining braking performance during repeated hard stops. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid one-piece rotor, while also reducing unsprung weight. The four-piston calipers offer increased clamping force over stock, working in conjunction with the larger rotors to provide a substantial improvement in braking capability.

Installing a big brake kit like this is a significant upgrade for any M3 owner looking to get the most out of their vehicle, especially if you track your car or drive it hard. It's important to follow the manufacturer's installation instructions carefully to ensure proper function and safety. This kit is designed to be a direct replacement for the rear braking system on the specified M3 models, offering a noticeable difference in pedal feel and stopping distance.
