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

This is the Brembo Rear GT Big Brake Kit for your 1978-1989 Porsche 930. It's a comprehensive upgrade designed to significantly improve your braking performance, especially when you're pushing the car hard. The kit includes everything you need to replace your stock rear braking components with a much more robust setup, featuring four-piston calipers and larger two-piece rotors.

At the heart of this kit are the Brembo four-piston calipers, known for their solid construction and consistent clamping force. These calipers work with the included 345x28mm two-piece rotors. The two-piece design helps manage heat more effectively than a single-piece rotor, reducing the risk of warping under heavy use. The rotors are drilled, which helps with heat dissipation and can also assist in clearing dust and gas from the pad surface, maintaining better contact. This combination means you get a stronger pedal feel and more reliable stopping power, whether you're on the street or the track.

When installing a big brake kit like this, it's important to ensure you have the correct hardware and follow the manufacturer's instructions carefully. This kit is a substantial upgrade, and it's designed to be a direct fit for the specified Porsche 930 models, but always double-check your specific vehicle's requirements. You'll notice a significant difference in how the car brakes, especially during repeated hard stops.
