Brembo 06-08 Z4 M-Coupe/Roadster Rear GTR BBK 4 Piston Billet 345x28 2pc Rotor Drilled- Nickel

This is the Brembo Rear GTR Big Brake Kit specifically for the 2006-2008 BMW Z4 M-Coupe and M-Roadster. It's a substantial upgrade designed to handle the demands of spirited driving and track use, offering a significant improvement in stopping power and heat management over the factory setup. The kit includes everything needed to convert your rear brakes to a high-performance system from a well-known name in braking technology.

At the heart of this kit are the 4-piston billet aluminum calipers, which are lighter and stronger than cast alternatives, allowing for better heat dissipation and reduced unsprung weight. These calipers grip a pair of 345x28mm two-piece rotors. The two-piece design separates the rotor ring from the hat, which helps manage thermal expansion and reduces the risk of rotor warping under heavy use. The rotors themselves are drilled, which helps to vent gases and heat away from the braking surface, providing more consistent performance, especially during repeated hard stops. The nickel finish on the rotors offers some corrosion resistance and a clean look.

Installing a big brake kit like this is a significant modification, and it's important to ensure all components are properly fitted and bled. This kit is designed as a direct replacement for the factory rear brake system, but it's always recommended to consult the manufacturer's installation guide for specific details and torque specifications. The improved thermal capacity and stopping force will make a noticeable difference when you need your Z4 M to slow down quickly and reliably.
