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

What you get with this Brembo GT Big Brake Kit (BBK) for the rear of your 2011-2012 1 Series M is a complete system designed for serious stopping power. This kit includes a pair of yellow 4-piston cast iron calipers, two-piece 345x28mm rotors with a Type-3 slotting pattern, and all the necessary hardware to get them installed. Brembo is well-known for its high-performance braking components, and this kit represents their top-tier offering for enthusiasts looking to significantly upgrade their vehicle's braking capabilities.

The calipers are cast iron, chosen for their strength and ability to handle the heat generated during aggressive driving. The two-piece rotor design is a notable feature; it separates the rotor friction surface from the hat, which helps to reduce weight and manage heat more effectively. This design also allows for easier replacement of just the rotor ring if needed down the line. The Type-3 slotting on the rotors is a specific pattern designed to help keep the pad surface clean and clear out gases and dust, which contributes to more consistent braking performance, especially under heavy use. The yellow finish on the calipers adds a distinct visual element to your wheel setup.

Installing a big brake kit like this is a significant upgrade that can change how your car feels and performs under braking. It's important to ensure you have the right tools and follow the manufacturer's instructions carefully during installation. Given the complexity and the performance expectations of this kit, it's often recommended to have a professional mechanic perform the installation if you're not experienced with brake system work. This kit is built for those who demand the most from their braking system.
