Brembo 17-23 540i Front GT BBK 6 Piston Cast 405x34 2pc Rotor Drilled-Fluo. Yellow

If you're looking to significantly improve your BMW 540i's braking performance, especially for spirited driving or track use, this Brembo GT Big Brake Kit is a serious upgrade. This kit replaces your factory front brake components with larger, more capable parts designed to handle higher temperatures and provide more consistent stopping power. It’s built for drivers who demand more from their vehicle's braking system.

At the heart of this kit are the 6-piston GT calipers, which offer increased clamping force over stock. These are paired with massive 405x34mm two-piece rotors. The two-piece design helps manage heat by allowing the rotor and hat to expand independently, reducing the risk of warping. The rotors are drilled, which helps with heat dissipation and can also assist in clearing dust and gas from the pad surface during hard braking. This entire assembly is finished in a bright, fluorescent yellow, adding a distinct visual flair to your vehicle.

This kit includes everything needed for the front axle to get your 540i stopping with confidence. The calipers are cast from aluminum for a good balance of strength and weight. When installing a kit of this caliber, it's always a good idea to consult the manufacturer's instructions carefully, as proper setup is crucial for optimal performance and safety. You'll notice a substantial difference in pedal feel and fade resistance, especially during repeated hard stops.
