Brembo 99-04 996 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type1-Silver

If you're looking to significantly upgrade the braking performance of your 1999-2004 Porsche 911 (996), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to replace your factory rear brake components with a much larger and more capable setup, providing improved stopping power and heat management for spirited driving or track use.

At the heart of this kit are the massive 345x28mm two-piece rotors. These are larger than stock, which means they can dissipate more heat and offer a larger surface area for the pads to grip. The rotors feature a slotted design, which helps to sweep away dust and gas that can build up between the pad and rotor surface during hard braking. This slotting pattern is Brembo's Type 1, and the rotors themselves are cast iron, known for their durability and heat handling. The calipers are a robust 4-piston cast aluminum design, offering increased clamping force over the factory calipers. The two-piece rotor construction allows for better thermal management as the hat and rotor can expand independently, and it also makes replacement easier down the line. The calipers come in a silver finish, adding a clean look behind your wheels.

This kit is a comprehensive upgrade, and while it's designed as a direct replacement for the rear of the 996, it's important to ensure you have the correct wheel clearance for the larger calipers and rotors. Installation will involve replacing your existing rear brake lines, rotors, calipers, and pads with the components included in this kit. For optimal performance, consider pairing this rear kit with a front Big Brake Kit from Brembo.
