Brembo 08-17 S5/09-16 S4 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-Black

Brembo is well-known for making high-performance braking components, and this Rear GT Big Brake Kit (BBK) is a prime example of their expertise. If you're looking to significantly upgrade the stopping power and heat management on your 2008-2017 Audi S5 or 2009-2016 Audi S4, this kit is designed to do just that. It replaces your factory rear brakes with a more robust system capable of handling demanding driving conditions.

This kit features a pair of Brembo's 4-piston GT calipers, which offer increased clamping force over stock calipers. These calipers are paired with 2-piece, 380x28mm slotted rotors. The larger rotor surface area and thickness help dissipate heat more effectively, reducing the risk of brake fade during aggressive use. The Type 1 slotting pattern on the rotors is designed to help sweep away dust and gas buildup, maintaining consistent pad contact and performance. The calipers themselves are cast from a strong material for durability and are finished in black for a clean, performance-oriented look.

Included in this kit are the calipers, rotors, and all necessary hardware for installation. This is a comprehensive upgrade for the rear of your vehicle, aimed at drivers who demand more from their braking system. For optimal performance and safety, it's always recommended to have this kit installed by a qualified technician and to follow the manufacturer's specific installation and bedding-in procedures.
