Brembo 06-10 M5/06-10 M6 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type3-Silver

The 380x28mm, two-piece rotor design in this Brembo GT Big Brake Kit is a key element for managing heat during aggressive driving. This kit is specifically for the rear of your 2006-2010 BMW M5 or M6, offering a significant upgrade over stock braking components. The four-piston calipers are cast from high-grade aluminum, chosen for its strength and lighter weight, which helps reduce unsprung mass. This contributes to better overall vehicle dynamics and handling.

Each caliper houses four pistons, precisely sized to work with the 380x28mm rotors. These rotors are slotted with Brembo's Type 3 pattern, which helps to vent gases and dust away from the pad surface. This venting action is crucial for maintaining consistent braking performance, especially under heavy use like track days or spirited canyon runs. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat independently from the iron friction ring, reducing the risk of rotor warping.

This kit is a comprehensive solution for those looking to significantly enhance their vehicle's braking capabilities. It includes everything needed for installation, ensuring a direct fit for the specified M5 and M6 models. When installing a big brake kit, it's always a good idea to consult the manufacturer's detailed instructions to ensure proper setup and bleeding of the brake system.
