Brembo 06-09 997.1 GT3 Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type3-Fluo. Yellow

If you're tracking your 2006-2009 Porsche 911 GT3 or pushing its limits on the street, upgrading the rear braking system is a critical step. This Brembo Big Brake Kit is designed specifically for the 997.1 GT3 rear axle, offering a substantial improvement in stopping power and heat management. It features robust 4-piston calipers and large 380x28mm two-piece rotors, built to handle the demands of spirited driving and track use.

The calipers in this kit are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for braking force. They are paired with two-piece rotors, where the iron braking surface is attached to an aluminum hat. This design allows for better thermal management, as the hat can dissipate heat more effectively than a solid one-piece rotor, and it also helps reduce weight. The rotors are slotted with Brembo's Type 3 pattern, which is known for its effectiveness in clearing dust and gas from the pad surface, ensuring consistent grip even under heavy braking. The calipers come in a distinctive Fluorescent Yellow finish, adding a visual upgrade to match the performance gains.

This kit is a comprehensive rear-axle upgrade. It includes everything needed to replace your factory rear braking components with a high-performance setup. Proper installation is key to realizing the full benefits of this system, so refer to the manufacturer's instructions for detailed guidance. The substantial rotor size and caliper piston count work together to increase clamping force and thermal capacity, giving you more confidence when braking late into corners or during repeated hard stops.
