Brembo 08-13 M3 (E90/E92/E93) Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1- Yellow

The 380x28mm two-piece rotor design in this Brembo GT Big Brake Kit is a key feature, helping to manage heat more effectively than a single-piece rotor. This is crucial for the rear of your 2008-2013 BMW M3 (E90/E92/E93) when you're pushing the car hard, whether on the track or during spirited drives on winding roads. The kit includes four-piston calipers, which offer more clamping force than the stock setup, translating to improved stopping power and better pedal feel.

Brembo is known for its high-performance braking systems, and this GT kit is built to match that reputation. The calipers are cast aluminum, keeping unsprung weight down while maintaining rigidity. The rotors are slotted, which helps to clear out brake dust and gases that can build up between the pad and rotor surface, ensuring consistent performance even under heavy braking. This kit is designed to be a significant upgrade over the factory braking system, providing a more confident and controlled stopping experience.

When installing a big brake kit like this, it's important to ensure you have the correct brake lines and potentially a master cylinder upgrade to take full advantage of the increased clamping force. Refer to the manufacturer's installation instructions for specific details regarding brake fluid types and bleeding procedures to achieve optimal performance from your new Brembo system.
