Brembo 06-10 M5/06-10 M6 Rear GTS BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-Black HA

This Brembo Rear Big Brake Kit (BBK) includes everything you need to significantly upgrade your vehicle's rear braking system. You'll get a pair of 380x28mm two-piece slotted rotors, a set of four-piston cast aluminum calipers finished in black with HA (High-performance Aluminum) coating, and all the necessary hardware for installation. This kit is designed for those who demand more from their brakes, whether it's for spirited driving or track use, offering a substantial improvement over stock components.

The two-piece rotor design is a notable feature, separating the rotor ring from the hat. This construction helps manage heat more effectively and can reduce unsprung weight compared to a single-piece rotor. The Type 1 slots on the rotor surface are engineered to help vent gases and dust away from the pad surface, which maintains consistent braking performance, especially under heavy use. The four-piston calipers are built for strength and rigidity, providing a solid foundation for the brake pads to apply even pressure to the rotor, leading to more controlled and powerful stops. The black HA coating on the calipers not only looks sharp but also offers added protection against corrosion and heat.

When installing a big brake kit like this, it's important to ensure proper fitment with your existing wheels, as the larger calipers and rotors can take up more space. Refer to the manufacturer's installation guide for specific details on mounting and any required modifications. This kit represents a significant investment in your vehicle's performance and safety, offering a noticeable difference in stopping power and heat management.
