Brembo 06-09 997.1 GT3/GT3RS (Excl PCCB) Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type3-Black

This Brembo GT Big Brake Kit is specifically for the 2006 through 2009 Porsche 997.1 GT3 and GT3RS models, excluding those equipped with Porsche Ceramic Composite Brakes (PCCB). It's a comprehensive rear brake upgrade designed to handle the demands of high-performance driving and track use, offering a significant improvement over the stock braking system. The kit features a robust 4-piston caliper design paired with a substantial 380x28mm two-piece rotor, providing increased thermal capacity and stopping force.

The calipers are cast from high-strength aluminum, a material chosen for its excellent strength-to-weight ratio, which helps reduce unsprung mass. They are engineered to provide consistent clamping force even under extreme heat. The two-piece rotors are constructed with a cast iron friction ring and an aluminum hat, a design that helps manage heat expansion and reduces overall weight. The friction rings are slotted, which aids in venting gases and dust away from the pad surface, maintaining optimal friction and preventing glazing during hard braking. This specific kit includes Brembo's Type 3 black finish rotors, known for their aggressive slotting pattern and enhanced cooling properties.

When installing this kit, it's important to note that it is designed as a direct replacement for the factory rear brake components on the specified 997.1 GT3 models, provided they do not have PCCB. The kit includes the necessary calipers, rotors, and mounting hardware to complete the rear brake upgrade. For optimal performance and safety, it is recommended to have this kit installed by a qualified technician and to follow the manufacturer's specific installation and bedding-in procedures. This upgrade is a substantial investment for drivers looking to maximize their vehicle's braking performance and reliability on the track or during spirited driving.
