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

Brembo is a name many people trust when it comes to stopping power, and they're known for making serious brake components. This Rear GT Big Brake Kit is a prime example of that expertise, designed to give your 2008-2017 Audi S5 or 2009-2016 Audi S4 a significant upgrade in braking performance. If you're looking to improve how your car handles hard braking situations, especially if you've modified your vehicle or plan on tracking it, this kit is built for that purpose.

At the heart of this kit are the four-piston calipers, which offer more clamping force than stock calipers. These work with the large 380x28mm two-piece rotors. The rotors are drilled, which helps dissipate heat and can also help clear dust and gas away from the pad surface during aggressive use, leading to more consistent stopping power. The two-piece design allows for better thermal management between the rotor and the hat, reducing the chance of warping under heavy load. This whole setup is designed to handle the demands of spirited driving and track use, providing a solid and reliable braking experience when you need it most.

When you're installing a kit like this, it's a good idea to have a full brake fluid flush done with high-temperature fluid to get the most out of the new components. This Brembo kit is a substantial upgrade for drivers who push their cars hard and demand the best from their braking system.
