Brembo 08-17 S5/09-16 S4 Front GT BBK 6 Piston Cast 380x32 2pc Rotor Slotted Type1-Black

If you're looking to significantly improve your Audi S5 or S4's braking performance, especially for track days or spirited driving, a Big Brake Kit (BBK) like this Brembo GT kit is a serious consideration. This kit replaces your factory front brake components with larger, more capable parts designed to handle higher temperatures and provide more consistent stopping power under demanding conditions. The heart of this kit is the massive 380x32mm two-piece rotor, which offers a larger surface area for heat dissipation and a stronger foundation for braking force.

This Brembo GT kit features a robust 6-piston caliper, known for its stiffness and ability to apply even pressure across the larger pad surface. The calipers are cast from high-strength aluminum for a good balance of durability and weight savings, and they come finished in a sleek black. The two-piece rotor design is beneficial because it allows the aluminum hat to expand and contract independently of the iron braking surface, which helps reduce the risk of rotor warping under extreme heat. These rotors are also slotted with Brembo's Type 1 pattern, which helps to sweep away dust and gas that can build up between the pad and rotor, maintaining optimal friction and preventing fade.

Installing a kit like this is a significant upgrade and typically requires specific tools and knowledge. It's designed to be a direct replacement for the factory mounting points on the specified Audi models, but you'll want to ensure you have all the necessary hardware and follow the manufacturer's installation instructions carefully. This Brembo GT Big Brake Kit is a well-built system aimed at drivers who push their vehicles hard and demand the best from their braking system.
