PFC Rotors: Just installed on my .1 (info and p/n's)

Just got done with the install of the front rotor install on my .1GT3 (non-PCCB). **.1PCCB and .2 steel and PCCB have 380mm front so they require different p/n's as do 5 bolt versus CL**
I went with this setup as I really like the PFC pads (mate perfectly in the swept area with these rotors) and the other options out there just cost more for the same result. A word of caution though for those that also run street pads or anything other than PFC pads......you can ONLY use PFC pads with the PFC rotors due to the swept area of the rotor. Stock pads are taller and will not fit.
One more word of caution.....if you want "matching" F&R you either need to lose your e-brake or run stock rotors for the rear as the PFC hats will NOT accommodate the e-brake.
One last thing, there are 2 different setups for the PFC rotors. There are the "Direct-Drive Dimpled" and the "Direct-Drive Slotted". The difference is that the slotted setup is a true floating setup where the dimpled setup is not. The dimpled setup attached the rotor to the hat only whereas the slotted has a hat on the front side and another aluminum ring on the backside that when installed allows for some (a few mm) of play on the rotor inside that assembly producing the true floating 2-piece setup. I have run both setups on my 6GT3 and unless you are racing (especially enduros) there is no significant advantage to going with the slotted floating setup. It's roughly 50% more in price and that price gets you 2mm thinner rotors to allow you to run the 19mm pads (versus the standard 17mm pads) and it gets you 0.8 pounds less per side in weight.
The part numbers for the .1GT3 without PCCB are:
Starter Set (comes with both hat and rotor)
350.068.87
350.068.88
Replacement Rotors
350.34.0060.27
350.34.0060.28
Replacement Hats
206.157.270.12 (same for both sides)
Specs:
Complete assembly --> 21.0#
Rotor Thickness -->34mm (FYI...32mm for slotted)

The slotted setup also does NOT come preassembled like the dimpled so you have to build them the first time (I think my helper got bored
)

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

If I am not mistaken the dimpled are 4 mm thicker then the slotted. So with the slotted you can fit 19mm pads instead of 17mm.
The slotted rotors should also be slightly lighter.
The rotors last about 20-24 days vs 16-20 oem on the .2's.

I stated that in the 1st post. Dimpled are 34mm and slotted are 32mm and 0.8 pounds lighter per corner. Verified with a micrometer an scale. They are 2mm different to accommodate the 2mm thicker enduro pad

We run a 378.32.006.45/6 sprint rotor......the 32 is thickness......7819.08.19.44 is the correct pad for the rotor.....19mm thick material
There is also a 378.34.006.45 endurance rotor that works of rour cars........the 34 is the tickness, 7819.08.17.44 is teh correct pad for that rotor......17 mm thick material
I asked PFC if we would get any more life out of the 34mm disk, they said not really, better for DE to use 32mm disk
379.34.0066.43/44 is the dimpled street rotor for our cars, larger sweep.....uses 0991.08.17.44 pad for correct sweep area
Better off.....let me handle technical questions, I just tell you what to buy

Interesting that the dimpled rotors have a bigger contact area for the (if you order the right one that is) brake pad, compared to the slotted ones.
