Brembo 08-13 M3/11-12 1M Front GT BBK 6 Piston Cast 365x34 2pc Rotor Slotted Type1-Black

The 365x34mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its ability to handle the heat generated during aggressive driving. This kit is built for performance vehicles like the 2008-2013 BMW M3 and the 2011-2012 1M, where stopping power and heat management are critical.

This kit features a six-piston caliper design, which distributes braking force more evenly across the larger rotor surface. The calipers themselves are cast aluminum, offering a good balance of strength and light weight. The rotors are slotted, a design that helps to vent gases and dust away from the pad surface, maintaining consistent friction and preventing glazing, especially under heavy use. The two-piece rotor construction allows the rotor ring to expand and contract independently of the hat, which can help reduce stress and prevent warping over time.

When installing a kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully, as it involves significant changes to your vehicle's braking system. This kit is designed to provide a substantial upgrade in braking performance for track days or spirited driving, offering improved fade resistance and stopping power compared to stock components.
