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

Brembo is a name synonymous with high-performance braking systems, and their GTS Big Brake Kits are a testament to that reputation. This rear kit is designed for enthusiasts looking to significantly upgrade their stopping power and heat management on their 2008-2017 Audi S5 or 2009-2016 Audi S4. It's a comprehensive package that replaces key components of your factory braking system with race-proven technology.

At the heart of this kit are the 4-piston calipers, known for their solid construction and ability to apply consistent pressure across the rotor surface. These calipers work in tandem with the 380x28mm two-piece rotors. The two-piece design helps manage heat more effectively by allowing the rotor and hat to expand independently, reducing the risk of warping. The rotors themselves feature a Type 1 slotting pattern, which helps to sweep away dust and gas buildup, maintaining optimal pad contact and consistent braking performance, especially during demanding use. The black finish on the calipers adds a subtle, performance-oriented aesthetic to your vehicle.

This kit includes everything needed to perform a substantial brake upgrade. You'll find the calipers, the two-piece slotted rotors, and all the necessary hardware for installation. While this is a direct fit for the specified Audi models, it's always a good idea to refer to the manufacturer's installation guide for any specific torque values or procedures to ensure a safe and effective installation.
