Figured it out... https://rennlist.com/forums/997-gt2-...clunk-diy.html
Randy or anyone else, can someone explain how does the bevel washer prevents the rotor from floating. If I'm looking at the design properly and understanding correctly the bevel/belleville washer goes in between the hat and the hold down ring. Therefore it creates even more space between the hat and the ring, which I would assume creates even more space for the rotor to float/clunk.
I'm having a hard visualizing how that would stop the floating. I have washers sitting in my garage and contemplating putting them in but wanted to check before doing so. By the way I'm talking about the V2 slotted rotors, not the V1/direct drive ones which use the bobbins.

For what it is worth I run the slotted. I have been through two sets of front rotors and never cracked one. Just run them until the slots disappear. I run my pads until they hit backing plate.
Reter had dimpled on his car for the first set (he now runs slotted). The rotor cracked all the way through before the dimples were gone.
I believe the dimpled is more of a street version, slotted more of the track version.......this is what a PFC engineer told me at PRI. For 997.2 GT3 the dimpled and slotted fit in this hat. The dimpled takes a larger pad, since swept area is slightly larger
For .2 cars slotted and diimpled use the same hat. If you remove the bevel washer it is a floating, if you keep the bevel washer in it prevents them from floating
PFC makes a rear brake hat (works with parking brake), but only sells it with a dimpled rotor....not seperate. So I stick with 997.2 turbo rotor
If anyone is wondering why my hat is gold......Reter and I had the two prototype PFC hats from Orbit

OK so a couple years later what's the experience with PFC slotted race rotors? How many track days (TD) are you getting out of the rotors? How long have the hats held up? Still using them?
My StopTech rotors were good for 24-30 TD but a couple times hats were shot when rotors were shot so needed full replacement. The cheap ATE rotors came in at hefty 26.5 lbs but lasted 50 TD DE and 28 TD with mix of DE and race. Considering PFC or AP for next season to reduce weight.
Appreciate any further input based on your experience. Thanks.

1. The inability to use stock pads for street driving on the PFC
2. The lack of a rear setup as they do not have a hat that will clear the e-brake. Sorry but I'm not giving up my ebrake on a street car.
I took my PFC set off and now they just sit in the garage as very expensive paperweight
