Brembo 06-08 RS4 Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type-1-Silver

If you're looking to significantly upgrade the stopping power on your 2006-2008 Audi RS4, this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to provide a substantial improvement in braking performance, especially under demanding conditions where heat and repeated stops can overwhelm stock components. It's a comprehensive package that addresses the entire rear braking system to work as a cohesive unit.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over the factory calipers. These calipers work with large 380x28mm two-piece rotors. The rotors are slotted, which helps to dissipate heat and gasses that build up during hard braking, keeping the pads in better contact with the rotor surface for more consistent stopping power. The two-piece design also helps manage heat and can reduce unsprung weight compared to a solid, one-piece rotor. The silver finish on the calipers adds a clean, performance-oriented look behind your wheels.

This Brembo kit is a complete rear brake solution. It includes everything needed to install the larger calipers and rotors, ensuring proper fitment and function. When upgrading to a big brake kit like this, it's always a good idea to ensure your front brakes are also up to the task, or consider upgrading them as well to maintain a balanced braking system. Refer to the manufacturer's installation instructions for specific details on mounting and setup.
