Brembo 11-12 1M Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-3-Black

If you're looking to significantly upgrade the braking performance on your 2011-2012 BMW 1M, this Brembo GT Big Brake Kit is a serious consideration. This kit focuses on the rear axle, providing a substantial improvement in stopping power and heat management. It's designed for drivers who push their vehicles hard and demand consistent, reliable braking under demanding conditions.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over stock calipers. These are paired with a 2-piece rotor assembly, featuring a 345x28mm disc size. The 2-piece design allows for better thermal management as the rotor can expand and contract more freely, and it also helps reduce unsprung weight compared to a single-piece rotor. The rotors themselves are slotted with Brembo's Type-3 pattern, which helps to vent gases and heat away from the pad surface, maintaining consistent friction and preventing fade during repeated hard stops. The black finish on the calipers and the slotted rotors give your vehicle a distinct, performance-oriented look.

This Brembo GT Big Brake Kit is a comprehensive upgrade. It includes everything needed to install the rear big brake system, ensuring a cohesive and effective braking solution. When undertaking a brake upgrade of this magnitude, it's always recommended to consult the manufacturer's installation guide for specific procedures and torque specifications to ensure optimal performance and safety.
