Brembo 17-23 540i Front GT BBK 6 Piston Cast 405x34 2pc Rotor Slotted Type1-White

This Brembo GT Big Brake Kit for your 17-23 540i includes everything you need to significantly upgrade your front braking system. You'll get a pair of six-piston calipers, two 405x34mm two-piece slotted rotors, and all the necessary hardware to get them installed. This kit is designed to replace your factory front brakes, offering a substantial improvement in stopping power and heat management.

The heart of this kit is the six-piston caliper, which uses larger pistons to apply more even pressure across the brake pad surface. This translates to more consistent braking force, especially under heavy use. The rotors are a two-piece design, with a cast iron friction ring bolted to an aluminum hat. This construction helps reduce weight and allows the rotor to expand and contract more freely as it heats up, which can help prevent warping. The Type 1 slots on the rotor surface are designed to help clear out dust and gas that can build up between the pad and rotor, maintaining optimal contact and improving wet-weather performance. The calipers come in a clean white finish, giving your wheels a more aggressive look.

Upgrading to a big brake kit like this is a significant change that can really transform how your 540i feels on the road, especially if you do spirited driving or track days. Because this is a complete kit, it's designed to be a direct replacement for your factory front brake components, simplifying the installation process. Make sure to follow the manufacturer's installation instructions carefully for proper setup.
