Brembo 11-12 1M Rear GTS BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-3-Black HA

This is the Brembo Rear GTS Big Brake Kit for the 2011-2012 BMW 1M. It's a comprehensive upgrade designed to significantly improve your braking performance, especially under demanding conditions. The kit includes a pair of four-piston calipers, large two-piece rotors, and all the necessary hardware to get them installed. If you're looking to get the most out of your 1M on the track or during spirited driving, this kit offers a substantial step up from the factory setup.

At the heart of this kit are the 380x28mm two-piece rotors. These are slotted with Brembo's Type-3 pattern, which helps to vent gases and dust away from the pad surface. This keeps the pads making consistent contact with the rotor, which is crucial for maintaining braking power when things get hot. The calipers themselves are a four-piston cast aluminum design, offering a strong and lightweight housing for the brake pads. The 'HA' designation in the part number typically refers to a specific finish or coating, in this case, a black finish on the caliper housing, adding a clean look to your wheel well.

This kit is a complete rear brake solution. It's designed to be a direct fit for the 2011-2012 BMW 1M, meaning it bolts on without requiring major modifications to your suspension or chassis. When installing a big brake kit like this, it's always a good idea to have a fresh set of brake fluid on hand and to follow the manufacturer's specific installation instructions carefully to ensure optimal performance and safety.
