Brembo 78-79 930/80-89 930 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Drilled-Black

Brembo is well-known for making high-performance braking components, and this Rear GT Big Brake Kit (BBK) continues that tradition. If you're looking to significantly upgrade the stopping power and thermal capacity of your 1978-1979 or 1980-1989 Porsche 930, this kit is engineered for that purpose. It replaces your stock rear braking system with a more robust setup designed to handle demanding use.

This kit features a pair of Brembo's 4-piston cast aluminum calipers, which offer increased clamping force over smaller factory calipers. These calipers work with substantial 345x28mm two-piece rotors. The rotors are drilled, which helps dissipate heat and gasses, and they are finished in black. The two-piece design allows for better heat management and can make rotor replacement simpler down the line. This setup is designed to provide improved braking performance, especially under repeated hard stops where heat can become a major factor.

When installing a big brake kit like this, it's important to ensure proper fitment with your specific wheel setup, as the larger calipers and rotors can require more clearance. This kit is a significant upgrade for enthusiasts looking to maximize their vehicle's braking capabilities.
