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

This Brembo big brake kit for the rear of your 2006-2008 BMW Z4 M-Coupe and M-Roadster includes everything you need to significantly upgrade your braking performance. You get a pair of black-finished, 4-piston cast aluminum calipers, two 345x28mm two-piece rotors that are drilled for heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear braking components with a much more robust setup, giving you improved stopping power and better heat management, especially during spirited driving or track use.

The calipers are constructed from cast aluminum, which keeps them strong yet relatively lightweight. The two-piece rotor design is a notable feature; it separates the braking surface from the hub assembly, allowing for better thermal expansion and reducing the risk of rotor warping. The drilled pattern on the rotors helps to vent gases and heat away from the braking surface, which is crucial for maintaining consistent performance under heavy braking. Brembo is a well-known name in braking systems, and this kit represents their GTS line, indicating a focus on enhanced performance for demanding applications.

Upgrading your rear brakes with a kit like this can make a real difference in how your Z4 handles under braking. It's a substantial modification that requires careful installation, so be sure to refer to the manufacturer's instructions for proper fitment and any specific tool requirements. While this kit focuses on the rear, it's part of a comprehensive approach to improving your vehicle's overall braking system.
