Mvez:
The APs for the 997.1 GT3 take the Pagid 2707 so the PF0991 would work since it's the same shape.
Some information on the PF rotors for the 997.2 GT3 and GT3RS:
The race rings are narrower as there are no provisions for the anti-rattle bevel springs/rings, as on the street type rings. The race rings are lighter and are full floating. The street rings are broader to support the bevel springs and therefore quieter for the street. Both are suitable for track day use. Also, the current hats offered by Performance Friction have round holes for the Porsche drive pins. The old style hats with the oval holes are no longer produced. All the hats we have are the current version produced by Performance Friction.
Slotted discs offer more bite and clean out a little better than the dimpled discs. The slotted discs are noisier and not recommended for the street. In the case of the race discs, they are lighter as they are 32.0mm thick (20.3 lbs) vs. 34.0mm thick (23.3 lbs) for the front dimpled discs. We weighed both on our UPS scale, while still in the boxes. The 34.0mm should have more thermal capacity so therefore should last longer.
The slotted race rings and hats are sold separately, not together as a kit like the dimpled. The slotted rotors are 378x32mm, the dimpled are 379x34mm. Performance Friction says to use the PF7819 pad with the 378x32mm slotted rotors. You can use either the PF0991 or PF7819 with the dimpled rotors.
We have stock in house of both the 378mm slotted (along with the hats) and the 379mm dimpled, along with plenty of the PF0991 in 08 compound, and PF7819 in 08, 06, and 01.
Hope this helps.

Schaffer:
Our rep at PF has told us that the 08s in the 7818 shape are special order here in the U.S. We have ordered the requisite number of sets and should have them in stock in about 3 weeks.
As far as using pads not specified for PCCB rotors, I haven't heard of anyone doing it. I know of several people who have removed the PCCBs and are running the Performance Friction rotors.

Mark (OG) or Clark (APEX),
Can you guys confirm a statement above indicating PFC rotors are good until the slots (or dimples) are gone? I have PFC floating slotted rotors (with anti-rattle bobbins) and they have significant cracking...but otherwise smooth...can they wear all the way down till the slots are gone, regardless of cracking?
Thanks!

They can wear down till the slots or dimples are gone. But, if there are cracks out to the outer edge, or inside to where they attach to the hat, it is time to replace. How many days do you have on your rotors? Can you post a photo?
