Brembo 06-08 RS4 Rear GTS BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-3-Black HA

This is the Brembo 4-piston rear Big Brake Kit (BBK) specifically for the 2006-2008 Audi RS4. If you're looking to significantly upgrade your RS4's braking performance, especially for track use or spirited driving, this kit is designed to make a substantial difference. It replaces your factory rear brake setup with larger, more capable components that can handle higher temperatures and provide more consistent stopping power.

At the heart of this kit are the 380x28mm two-piece rotors. These are larger in diameter and thicker than stock, which helps dissipate heat more effectively and resist fade during prolonged braking. The Type-3 slotting pattern on the rotors is a notable feature; these slots help to vent gases and dust away from the pad surface, maintaining a cleaner contact patch and improving braking consistency, especially under demanding conditions. The calipers themselves are a robust 4-piston cast aluminum design, providing increased clamping force over the factory calipers. This combination of larger rotors and more powerful calipers means you'll feel a more immediate and confident response when you apply the brakes.

This kit includes everything you need for installation, featuring the calipers, rotors, and necessary hardware. The black HA (High-Performance Aluminum) finish on the calipers not only looks sharp but is also chosen for its thermal properties. While this is a significant upgrade, it's designed as a direct fit for the 2006-2008 Audi RS4, meaning it bolts on without requiring extensive modifications. For those pushing their RS4 to its limits, this Brembo kit offers a well-built solution for improved braking performance and durability.
