Brembo 08-13 M3 (E90/E92/E93) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type-3-Silver

This is the Brembo GT Big Brake Kit for the rear of your 2008-2013 BMW M3 (E90, E92, E93). It's a complete system designed to significantly upgrade your M3's stopping power, especially under demanding conditions. The kit includes four-piston calipers, two-piece slotted rotors, and all the necessary hardware for installation, making it a comprehensive solution for enthusiasts looking for improved braking performance.

The calipers are cast from aluminum for a good balance of strength and weight, and they house four pistons to provide more clamping force than stock. These calipers work with the included 345x28mm two-piece rotors. The rotors feature Brembo's Type-3 slotting pattern, which helps to dissipate heat and gasses that build up during hard braking, keeping your brakes cooler and more consistent. The two-piece design allows the rotor ring to expand and contract independently of the hat, which can help reduce the risk of rotor warping over time. This kit is engineered to offer a noticeable improvement in braking feel and fade resistance, which is crucial for track use or spirited driving.

When installing this kit, you'll want to ensure you have the correct tools and follow the manufacturer's instructions carefully. This is a substantial upgrade, and proper installation is key to realizing its full performance potential. It's a well-built system from Brembo, a name known for its high-performance braking components.
