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

This Brembo GT Big Brake Kit for the rear of your 2006-2008 BMW Z4 M Coupe and Roadster includes everything you need to significantly upgrade your braking system. You'll get a pair of Brembo's cast 4-piston calipers, two-piece 345x28mm rotors that are drilled for better heat dissipation, and all the necessary hardware to get them installed. This kit is designed to replace your factory rear brakes with a much more robust setup, giving you improved stopping power and fade resistance, especially during spirited driving or track use.

The calipers are cast aluminum, which keeps them strong yet relatively lightweight. They house four pistons, providing more clamping force than a typical two-piston caliper. The two-piece rotor design is a notable feature; it separates the rotor friction surface from the hat, allowing for better thermal management and reducing the risk of rotor warping under heavy load. The drilled surface on the rotors helps to vent gases and heat away from the pad surface, which is crucial for maintaining consistent braking performance when things get hot. This kit is a substantial upgrade over stock, offering a more confident and controlled braking experience.

When installing a big brake kit like this, it's always a good idea to refer to the manufacturer's installation instructions for specific details. Ensure you have the correct tools and consider flushing your brake fluid with a high-performance DOT 4 fluid to get the most out of this Brembo system. This kit is a serious investment in your Z4 M's performance and safety.
