Brembo 04-10 5-Series (Excl. xDrive/M5) Front GT BBK 8 Piston Cast 380x34 2pc Rotor Drilled-Red

The 380x34mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, chosen for their ability to handle heat without warping. This kit is specifically designed for the front axle of 2004-2010 5-Series BMWs, excluding the xDrive and M5 models, and aims to significantly improve your braking performance.

At the heart of this system are the massive 8-piston calipers, which apply more even pressure across the larger rotor surface. This increased clamping force, combined with the drilled rotor design that helps dissipate heat and gas, means you get more consistent stopping power, especially during repeated hard braking. The two-piece rotor construction allows the aluminum hat to expand and contract independently of the iron braking surface, further reducing stress and the risk of cracking under extreme thermal loads. This kit is a substantial upgrade for drivers looking for a noticeable difference in braking feel and capability.

When installing a kit of this caliber, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. This kit is designed to be a direct fit for the specified models, but it's always a good idea to consult the included documentation for any specific requirements or recommendations regarding brake fluid and bedding-in procedures to get the most out of your new Brembo system.
