Brembo 17-23 540i Front GTR BBK 6 Piston Billet 405x34 2pc Rotor Slotted Type1-Nickel

This is the Brembo GTR Big Brake Kit for the front of your 2017-2023 BMW 540i. This kit is designed for serious performance driving, offering a substantial upgrade over the factory braking system. It features a 6-piston caliper setup with massive 405x34mm two-piece rotors, engineered to handle extreme heat and provide consistent stopping power when you need it most.

The calipers themselves are billet aluminum, which is both strong and lightweight, and finished with a nickel plating for corrosion resistance and a clean look. The rotors are a two-piece design, meaning the hat and rotor ring are separate. This design helps manage heat expansion and reduces weight compared to a single-piece rotor. They are slotted with Brembo's Type 1 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction and preventing fade during repeated hard stops. This kit is a complete front-end solution, aiming to provide a significant improvement in braking performance and feel for track days or spirited driving.

When installing a kit of this caliber, it's important to ensure you have the correct tools and follow the manufacturer's instructions closely. While this kit is designed as a direct replacement for the factory components, it's always a good idea to consult the included documentation for specific torque values and any potential clearance checks with your wheels. This GTR kit represents Brembo's commitment to high-performance braking, offering a well-built and thoroughly tested solution for demanding applications.
