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

This is the Brembo 4-piston rear brake kit for the 2006-2008 Audi RS4. It's designed to give your RS4's rear brakes a significant upgrade in stopping power and heat management, crucial for a car with its performance capabilities. The kit includes everything you need to replace your factory rear rotors and calipers with a much more robust setup from Brembo, a name known for high-performance braking systems.

At the heart of this kit are the 4-piston calipers, which offer more clamping force than the stock units. These calipers work with large 380x28mm two-piece rotors. The two-piece design helps manage heat more effectively by allowing the rotor and hat to expand and contract independently, reducing the risk of warping. The rotors themselves are drilled, which helps to dissipate heat and gasses, keeping the pads biting consistently even under heavy use. The black finish on the calipers and the drilled pattern on the rotors give your RS4 a distinct, performance-oriented look behind the wheels.

This is a comprehensive big brake kit (BBK) designed for a direct fit on the 2006-2008 Audi RS4. It's a substantial upgrade intended for owners who push their vehicles hard and demand the best from their braking system. Ensure you have adequate clearance within your wheels for these larger components; consult Brembo's fitment guide for specific wheel size recommendations.
