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

The cast aluminum, 4-piston calipers in this Brembo GT Big Brake Kit are designed to handle the demands of the Z4 M-Coupe and Roadster. These calipers work with 345x28mm, 2-piece rotors that are drilled for improved heat dissipation. This kit is a significant upgrade for drivers looking to enhance their vehicle's braking performance, especially during spirited driving or track use.

Brembo engineers this kit with a focus on both stopping power and heat management. The larger rotor surface area and the multi-piston caliper design allow for more consistent braking force and better pedal feel, even under heavy use. The 2-piece rotor construction, featuring a cast iron friction ring and an aluminum hat, helps reduce unsprung weight and manage thermal expansion. The drilled rotor faces help to vent gases and water away from the pad surface, maintaining optimal friction.

This kit includes everything needed for installation, providing a comprehensive solution for upgrading your Z4 M's rear braking system. When installing a big brake kit, it's always a good idea to refer to the manufacturer's specific installation instructions to ensure proper fitment and function.
