Brembo 08-13 M3 (E90/E92/E93) Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-3-Black

The 380x28mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, chosen for their ability to handle heat without warping. This kit is specifically for the 2008-2013 BMW M3 models (E90, E92, and E93 chassis), giving you a significant upgrade over the factory braking system. The four-piston calipers are designed to clamp down on these larger rotors, increasing stopping power and heat dissipation.

Brembo's Type-3 slotted rotor design is a key feature here. The slots are machined into the rotor surface to help sweep away dust and gas that can build up between the pad and rotor during hard braking. This keeps the pad surface cleaner and allows for more consistent contact, which means more reliable stopping performance when you need it most. The two-piece rotor construction also helps manage heat, as the aluminum hat stays cooler than a solid iron rotor would, reducing the risk of rotor distortion.

This kit includes everything needed to install the rear braking upgrade on your M3. You'll find the calipers, the two-piece slotted rotors, and all the necessary mounting hardware and brake lines. This is a comprehensive package designed to give your M3 a substantial improvement in braking performance, suitable for track use or spirited driving where consistent, strong stopping power is essential.
