Brembo 08-13 M3 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1 - Fluo. Yellow

This Brembo GT Big Brake Kit for the rear of your 2008-2013 BMW M3 gives you everything you need to significantly upgrade your braking system. You get a pair of fluorescent yellow 4-piston cast aluminum calipers, two 380x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to provide a substantial improvement in stopping power and heat management, making it ideal for drivers who push their M3 hard on the track or demand the best performance on the street.

The calipers are Brembo's GT caliper design, known for their stiffness and consistent performance under heavy use. They feature a 4-piston configuration, which helps distribute braking force evenly across the larger 380x28mm rotors. These rotors are a two-piece design, meaning the hat is separate from the rotor ring. This construction helps reduce weight and allows for better thermal expansion, which can prevent warping. The Type 1 slotting pattern on the rotor surface is designed to help sweep away dust and gas, maintaining consistent pad contact and improving wet weather braking performance. The fluorescent yellow finish on the calipers adds a distinct visual flair to your vehicle's setup.

Installing a big brake kit like this is a significant upgrade, and it's recommended to have a professional mechanic perform the installation to ensure everything is set up correctly. This kit is engineered to work with your M3's existing master cylinder and brake lines, though some applications may benefit from braided stainless steel lines for improved pedal feel. With this Brembo kit, you're investing in a well-built system that offers a notable increase in braking performance and durability for your high-performance BMW.
