GiroDisc Porsche 991 Cup/GT4 Clubsport Slotted Rear Rings (For PFC/Porsche Hats) - D2-370

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.

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