Brembo 11-12 1M Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled- Yellow

If you're looking to significantly upgrade the braking performance on your 2011-2012 1 Series M, this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the factory setup. It centers around a pair of robust 4-piston calipers that provide more clamping force and better heat dissipation.

The kit includes 380x28mm two-piece rotors, which are drilled for improved cooling and weight savings. The two-piece design allows for better thermal management, as the rotor and hat can expand and contract independently. The calipers themselves are cast aluminum, keeping unsprung weight down while offering a solid foundation for the pistons. This particular kit comes with yellow calipers, adding a distinct visual element to your vehicle's wheel well.

Installing a big brake kit like this is a comprehensive upgrade. It's designed to be a direct fit for the specified vehicle, meaning no major modifications are typically needed for installation, though it's always recommended to consult the manufacturer's instructions. This kit represents a significant investment in your vehicle's performance and safety, providing the stopping power needed for more demanding driving scenarios.
