Brembo 06-08 Z4 M-Coupe/Roadster Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Black

The cast aluminum calipers in this Brembo GT Big Brake Kit feature a robust four-piston design, a key element for handling the increased thermal load generated during spirited driving or track use. This kit is specifically tailored for the rear of the 2006-2008 BMW Z4 M-Coupe and M-Roadster, aiming to provide a significant upgrade over the factory braking system. The larger 345x28mm two-piece rotors are drilled to help dissipate heat and reduce weight, contributing to more consistent stopping power when you need it most.

Brembo's GT BBK is built with performance in mind, utilizing high-strength materials and a design proven in demanding conditions. The calipers are finished in black, offering a clean, performance-oriented look behind your wheels. The two-piece rotor construction allows for better thermal management, as the aluminum hat can expand and contract independently of the iron friction ring, reducing the risk of rotor warping. This kit is a comprehensive solution for Z4 M owners looking to enhance their vehicle's braking performance for track days or aggressive street driving.

When installing this kit, it's important to note that it is a significant upgrade and may require adjustments to your vehicle's brake bias. Always refer to the manufacturer's installation instructions for proper fitment and any specific requirements. This kit is designed to work with the factory master cylinder, but for optimal performance, especially with significant brake upgrades, consulting with a brake specialist is always a good idea.
