.2RS Added Brake Cooling = trackable PCCBs?
With the new NACA ducts cooling the brakes will PCCBs stay cool enough to prolong their life at the track making them financially equivalent to iron? Or does it make sense to order iron and upgrade to aftermarket CCBs to get the lighter weight and rebuildablity? If the latter, is there a spring rate difference to manage the lighter weight of PCCBs or are the spring rates the same for iron and PCCB? I know in an interview AP stated track drivers may still want to opt for iron for a lower cost of ownership. Just wondering if the ducts really add enough cooling to shift that cost?

If you're going to be doing a ton of HPDE events in the car I for one would purchase the AP Racing replacement calipers/pads. Cheaper in the long run no doubt.

Gen III PCCBs are perfectly fine for the track. As is.

Clearly they are perfectly fine for the track. Possibly better than iron due to less unsprung weight.
The question is how long do the rotors last? There doesn't seem to be any meaningful data about that. Not many people are ok with dropping $15K on brakes after some track days.

you can swap to ST rotors like I did. PCCB replacement is about $25K, not 15K AFAIK.
ST are 12K but the rears should last forever.
Fronts should be OK for 5 refurbishments and 20+ track days in between the refurbs. Refurb is $500 per corner.
I'm on day 12 of being very hard on the brakes...

For what it's worth, I know of a 991.1 GT3 owner with PCCBs who has gone through more engines (3) than OEM ceramic rotors (0)
Probably a good 20+ days of track time.
