GiroDisc Porsche 991 Cup, GT4 Clubsport Rear Rings for Factory Hats

These are direct replacement rear rings for the Porsche 991 GT3 Cup and all GT4 Clubsport factory race cars, for use with the Porsche/PFC factory hats and retaining ring hardware. They are direct replacements for PFC part numbers 380.30.0047.451 (left) and 380.30.0047.461 (right).

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 will plug-and-play with your existing hats without requiring the purchase of additional hardware.

Sold per pair. Hardware not included.

Diameter: 380mm
Thickness: 30mm
Minimum thickness: 28mm

Note: if you have GiroDisc hats, these are not the correct replacement rings. You will need our part number D2-238.
