Brembo 08-17 S5/09-16 S4 Rear GTR BBK 4 Piston Billet 380x28 2pc Rotor Slotted Type1 - Nickel

If you're looking to significantly upgrade the stopping power on your Audi S5 or S4, especially for track days or spirited driving, this Brembo GTR Big Brake Kit is a serious consideration. This rear kit is designed to handle the demands of high-performance driving, offering improved heat dissipation and consistent braking force when you need it most. It replaces your factory rear brake setup with a much more robust system, built for performance and durability.

At the heart of this kit are the 4-piston GTR calipers, crafted from billet aluminum for a strong yet lightweight foundation. These calipers work with 380x28mm two-piece rotors that feature a Type 1 slotting pattern. The slots on the rotor surface help to sweep away dust and gas that can build up between the pad and rotor, which means more consistent braking performance, especially under heavy use. The nickel finish on the rotors not only looks sharp but also offers some added corrosion resistance. This is a comprehensive kit designed to integrate seamlessly with your vehicle's existing systems while providing a substantial upgrade in braking capability.

When installing a big brake kit like this, it's important to ensure all components are properly fitted and bled according to the manufacturer's instructions. This kit is a significant investment in your vehicle's performance and safety, providing the confidence that comes with knowing your brakes can handle whatever you throw at them. It's a popular choice for those who push their vehicles hard and demand the best from their braking system.
