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

This Brembo GT Big Brake Kit is specifically for the rear of your 2008-2017 Audi S5 or 2009-2016 Audi S4. It's designed to give you a significant upgrade in stopping power and heat management, which is crucial if you're pushing your car hard or have made other performance modifications. This kit replaces your factory rear brake setup with a much more robust system featuring larger rotors and more powerful calipers.

At the heart of this kit are the Brembo 4-piston GT calipers, known for their solid construction and consistent performance. They clamp down on large 380x28mm two-piece rotors. The two-piece design helps manage heat better than a single-piece rotor, and the slotted surface on these Type 1 rotors helps to clear out brake dust and gas buildup. This means you get a more reliable and consistent bite, especially during repeated hard stops. The calipers come in a bright yellow finish, adding a distinctive look behind your wheels.

When installing a big brake kit like this, it's important to ensure you have the correct supporting components. While this kit includes the calipers and rotors, you'll want to confirm if any additional hardware or brake lines are recommended by Brembo for optimal performance and fitment on your specific S5 or S4 model. This is a substantial upgrade that will noticeably change how your car feels under braking, offering improved confidence and control.
