Brembo 09-13 X5M Front GT BBK 6 Piston Cast 405x34 2pc Rotor Slotted Type3-Red

The 405x34mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron with a slotted surface, designed to handle the extreme demands of the 2009-2013 X5 M. This kit replaces your factory front brake components with a high-performance setup featuring six-piston calipers and larger rotors, significantly increasing stopping power and heat dissipation.

This kit is built around Brembo's GT caliper, a popular choice for serious braking performance. The calipers are cast aluminum for a good balance of strength and weight, and they come finished in a vibrant red. The two-piece rotor design allows for better thermal management, as the aluminum hat can expand and contract independently of the iron braking surface, reducing the risk of rotor warping under heavy use. The slots on the rotor surface help to vent gases and debris, maintaining consistent pad contact and improving wet weather performance.

When installing a big brake kit like this, it's important to ensure you have adequate clearance for the larger calipers and rotors within your wheels. This kit is designed to be a direct replacement for the front axle, but it's always a good idea to confirm wheel fitment before installation. You'll notice a substantial difference in pedal feel and braking consistency, especially during repeated hard stops.
