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

This is the Brembo Rear GTS Big Brake Kit for the 2011 and 2012 BMW 1M. This kit is designed to give your 1M a significant upgrade in braking performance, especially for track use or spirited driving where consistent stopping power is crucial. It replaces your factory rear brake setup with a larger, more capable system that can handle higher temperatures and repeated hard braking.

At the heart of this kit are the 345x28mm two-piece rotors. The two-piece design allows for better heat dissipation and can reduce rotor warping over time compared to a single-piece rotor. These rotors are slotted, which helps to clear out brake dust and gas that can build up between the pad and rotor surface, maintaining a cleaner contact patch for more consistent braking. The calipers are a 4-piston cast aluminum design, offering increased clamping force over the stock calipers. The black HA finish on the calipers adds a subtle, performance-oriented look to your rear wheels.

This kit is a comprehensive upgrade, intended for owners who demand the best from their braking system. It includes everything needed to install the larger rotors and calipers, ensuring a direct fit for the 2011-2012 BMW 1M. Proper installation is key to realizing the full benefits of this high-performance brake kit.
