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

This Brembo GT Big Brake Kit for the 08-13 M3 (E90/E92/E93) rear includes everything you need to significantly upgrade your braking performance. You get a pair of red 4-piston GT calipers, two 380x28mm two-piece slotted rotors, and all the necessary hardware to get them installed. This is a comprehensive package designed to give your M3 a serious braking advantage.

The calipers are cast aluminum, which keeps them strong yet relatively light. They house four pistons, allowing for more even pad pressure across the larger 380x28mm rotors. These rotors are a two-piece design, meaning the hat and the friction surface are separate. This design helps manage heat and can reduce warping over time compared to a single-piece rotor. The slots on the rotor surface are Type-1, which are designed to help clear out dust and gas that can build up between the pad and rotor, maintaining consistent braking performance, especially during hard use.

Upgrading to a big brake kit like this is a substantial modification. It's ideal for M3 owners who track their cars or frequently drive in demanding conditions where consistent, strong braking is crucial. While the installation is more involved than a standard brake job, the payoff in terms of stopping power and heat management is considerable. Ensure you have the proper tools and refer to Brembo's installation guide for the best results.
