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

This is the Brembo Rear GT Big Brake Kit for the Porsche 930, covering model years 1978 through 1989. If you're looking to significantly upgrade your braking performance, especially for spirited driving or track use, this kit is designed to make a substantial difference. It replaces your stock rear braking components with a much more robust setup, featuring larger rotors and powerful calipers to handle increased heat and demand.

At the heart of this kit are the 4-piston cast aluminum calipers, which offer increased clamping force over smaller factory calipers. These are paired with 2-piece, 345x28mm rotors. The 2-piece design helps manage heat more effectively by allowing the rotor hat to expand and contract independently from the braking surface, reducing the risk of warping. The rotors themselves are drilled, which helps to dissipate heat and remove brake dust and gas from the pad surface, maintaining consistent stopping power. This kit is a comprehensive solution, aiming to provide improved stopping power and fade resistance.

When installing a big brake kit like this, it's important to ensure you have the correct supporting components. While this kit includes the calipers and rotors, you'll want to confirm compatibility with your existing brake lines and master cylinder, or consider upgrading those as well for optimal performance. Brembo is well-known for its high-performance braking systems, and this kit represents their GT line, which is geared towards enhanced track and street performance.
