GiroDisc Porsche 911 GT3 RS (992 w/36mm Thick Rotors Excl PCCB) Slotted Front Rings

GiroDisc replacement cast iron rotor rings for the Porsche 911 GT3 RS (992 w/36mm Thick Rotors Excl PCCB), front axle. When the iron is worn or heat-checked, you replace the rings and keep the hats — the reason a two-piece rotor is cheaper to own over time.

About replacement rings

• Rings only — aluminum hats are not included.
• New installation hardware (cap screws, hardened washers and anti-noise spring washers) is supplied. GiroDisc does not recommend reusing old hardware.
• Slotted friction surface with curved internal cooling vanes, same specification as the original assembly.

These rings are machined for GiroDisc hats and will not mount to factory center hats.
