DP95. Thanks for the response. You are quite right with the ate's (2005 Cayanne Turbo). I ended up ordering the fronts through RockAuto.com in Canada. $100.48 each for the fronts. Ended up ordering the rears for $227.00 from a Midas shop in Victoria, BC. I happen to know the owner (my brother). He will bring them to Kelowna in May for the Knox Hillclimb.
Harry Dogs Grrrrage was a tremendous help and had great pricing on the front and rear rotors as well! Rears through them were $210.00 each!

UPDATE: Thanks everyone for the advice. I went with slotted Cayenne S rotors (350 mm) for the front at around $250 for the pair and OEM rotors for the rear. I installed them along with the PFC08's this weekend and everything fit fine. I also bled the system using Motul 600 and then bedded in the new pads.
With a little temperature in the PFC's, they stop STRONG. I can't wait to try them out at COTA this weekend at the MVP event. Only downside is they do squeal pretty loudly when slowing to a stop. I'll drive them for a bit to see if it goes away, but at the current noise level I'll probably swap OEM back in until the next track event.

Or Motul 660. SRF is ancient technology and is subject to being hydroscopic more than the other two from what I've been told. But it is tried and true. I bleed as infrequently or less than SRF users with 660. Can't go wrong with any of those 3.

SRF dry boiling point 590 degrees
Motul RBF 600 dry boiling point 594 degrees
Motul RBF 660 dry boiling point 617 degrees
I have used and still do RBF 600 and never boiled the fluid
tried the SRF $$$ and didn't see any benefit except a much lighter wallet 
Just another point of view where I feel spending more $$ isn't always better.

You run tiny little disposable cars that only weight 2300 pounds 
I've literally seen everything from corvettes to 997 turbos boil Motul 600. And these are students running at student speeds. I know on paper it seems like the 600 should be work but for whatever reason it fails every time.
My only complaint, and it has nothing to do with performance, is that the Motul 660 comes out of the bottle dark. Hard to tell if its been compromised.

DP95. You bet, factory for the rear and "ate" for the front. Eddie has been great as well. Got a full set of PFC 08's as well as the trans 75A mounts. He even offered to mail the parts to me so I can avoid the UPS/FedX $$$$ at the border. Great service!

I hope you got GT3 rears, as I don't think the cayenne rears are compatible. Just the fronts. I've run a ton of cayenne fronts now. All the 350mm are great.
