These are direct replacement front rings for the Porsche 991 GT3 Cup and all GT4 Clubsport factory race cars, for use with the Porsche/PFC factory hats and hardware. They are direct replacements for PFC part numbers 380.32.0054.451 (left) and 380.32.0054.461 (right).

These rings are machined from a 72-vane casting, which offers improved durability and longevity over the factory-supplied 48-vane rings. They are manufactured with the same tooth-drive retention as the original rings and will plug-and-play with the factory hats and hardware.

Sold per pair. Hardware not included.

Diameter: 380mm
Thickness: 32mm
Minimum thickness: 30mm

Note: if you have GiroDisc hats, these are not the correct replacement rings. You will need our part number D1-238.
