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

This Brembo GT Big Brake Kit for the rear of your 2011-2012 BMW 1M includes everything you need to significantly upgrade your braking system. You'll get a pair of Brembo's well-known 4-piston GT calipers, a set of 380x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to give your 1M a serious boost in stopping power and heat management, crucial for spirited driving or track use.

The calipers are cast aluminum, keeping unsprung weight down while providing a solid foundation for the brake pads. The two-piece rotors feature a floating design, allowing the friction ring to expand and contract independently of the hat, which helps prevent rotor warping under extreme heat. The drilled surface on these rotors helps vent gases and heat away from the pad surface, contributing to more consistent braking performance, especially during repeated hard stops. Brembo is a name trusted in motorsports and high-performance vehicles for a reason; their components are built to handle demanding conditions and provide reliable stopping power.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. This kit is a substantial upgrade, and proper installation is key to realizing its full performance potential. You'll likely notice a significant improvement in pedal feel and a reduction in brake fade during aggressive driving. Check the included hardware list to ensure all components are present before beginning installation.
