Brembo 66-89 911S/SC/Carrera PISTA Rear Race BBK 4 Piston Forged328x32x53a 2pc Rotor T5-Clear HA

This is the Brembo PISTA rear race brake kit for 1966-1989 Porsche 911S, SC, and Carrera models. It's a serious upgrade designed for track use, featuring large 4-piston forged calipers and substantial 2-piece rotors to handle the extreme demands of racing. If you're pushing your classic 911 hard on the track, this kit offers a significant improvement in stopping power and heat management over stock components.

The kit includes Brembo's 4-piston forged aluminum calipers, which are lighter and stronger than cast alternatives, allowing for better heat dissipation and reduced unsprung weight. These calipers grip a 328x32mm 2-piece rotor assembly. The 2-piece design allows the rotor and hat to expand and contract independently, reducing the risk of rotor warping under intense heat. The rotor face has a T5-Clear HA finish, which is a surface treatment designed to protect against corrosion during storage and initial break-in, while also helping to keep the rotor surface clean. This setup is built to withstand repeated hard braking sessions without fade.

This is a comprehensive rear brake upgrade. Ensure you have adequate clearance within your wheels for the larger calipers and rotors; Brembo recommends checking wheel fitment before installation. This kit is intended for dedicated track use and may require modifications to your brake system for proper integration. Refer to the manufacturer's installation instructions for detailed guidance.
