These are direct replacement rings for the Porsche 991 GT3 Cup and all GT4 Clubsport factory race cars, for use with the Porsche/PFC factory hats and snap ring hardware.
With a higher 72-vane count, these rings offer a durability and longevity upgrade over the original 48-vane rings. Manufactured with the same tooth-drive configuration as the factory hats, these are plug-and-play with existing hats and need no additional hardware.
Hardware not included.
