Brembo 08-17 S5/09-16 S4 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type3- Yellow

This Brembo GT Big Brake Kit for the rear of your 2008-2017 Audi S5 or 2009-2016 S4 includes everything you need to significantly upgrade your braking system. You get a pair of yellow 4-piston GT calipers, two 380x28mm two-piece slotted brake rotors, and all the necessary hardware for installation. This kit is designed to replace your factory rear brake setup with a much more robust system, offering improved stopping power and heat management.

The calipers are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the 4 pistons. These pistons work together to apply even pressure across the larger 380x28mm two-piece rotors. The rotors themselves are slotted with Brembo's Type 3 pattern, which helps to vent gases and heat away from the pad surface, maintaining consistent braking performance even under heavy use. The two-piece design allows the rotor to expand and contract more freely with temperature changes, reducing the risk of warping and improving longevity. The bright yellow finish on the calipers adds a distinctive look behind your wheels.

Upgrading to a big brake kit like this is a substantial change that can make a noticeable difference in how your car feels when you slow down, especially during spirited driving or when carrying extra weight. Ensure you have adequate clearance for the larger calipers and rotors within your wheel setup. Refer to the manufacturer's installation instructions for detailed guidance on fitting this kit to your vehicle.
