Brembo 78-79 930/80-89 930 Rear GT BBK 4 Piston Cast 2pc 345x28 2pc Rotor Slotted Type-3-Black

This Brembo GT Big Brake Kit for the rear of your 1978-1979 and 1980-1989 Porsche 930 includes everything you need to significantly upgrade your braking system. You get a pair of four-piston aluminum calipers, two 345x28mm two-piece rotors with Type-3 slots, and all the necessary hardware for installation. This kit is designed to replace your stock braking components with a more robust setup, offering improved stopping power and heat management for spirited driving or track use.

The calipers are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. The two-piece rotors feature a cast iron friction ring bolted to an aluminum hat, reducing weight and allowing for better thermal management. The Type-3 slots on the rotors are a notable design choice; they help to sweep away dust and gas that can build up between the pad and rotor surface, ensuring more consistent braking performance, especially under heavy use. This design also helps to keep the rotor surface cleaner, which can contribute to longer pad life.

Installing a big brake kit like this is a substantial upgrade. It's important to ensure you have the correct tools and follow the manufacturer's instructions carefully, as brake system modifications require precision. This kit is a popular choice for 930 owners looking for a significant improvement in braking performance and feel, especially for those who push their vehicles hard.
