Brembo 06-08 Z4 M-Coupe/Roadster Rr GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type1-Silver

This is the Brembo Rear GT Big Brake Kit for the 2006-2008 BMW Z4 M-Coupe and M-Roadster. It's designed to significantly upgrade your rear braking system, offering more stopping power and better heat management than the factory setup. If you push your Z4 hard on the track or simply want the best possible braking performance for spirited street driving, this kit is a serious consideration.

At the heart of this kit are the Brembo 4-piston cast aluminum calipers. These are well-built units designed for strength and rigidity, which helps ensure consistent pedal feel even under heavy braking. They work in conjunction with a pair of 2-piece, 345x28mm slotted rotors. The two-piece design allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping. The slots on the rotor surface help to sweep away dust and gas that can build up between the pad and rotor, maintaining optimal friction and preventing fade during repeated hard stops. The Type 1 silver finish on the calipers adds a clean, performance-oriented look to your rear wheels.

This kit includes everything you need to install the upgraded rear braking system. You'll find the calipers, rotors, mounting brackets, and all necessary hardware. While this is a direct bolt-on kit for the specified Z4 models, it's always a good idea to consult the manufacturer's installation guide for specific torque values and any other recommended procedures. Upgrading your rear brakes like this can make a notable difference in your car's overall braking balance and performance.
