I can’t tell you what the better setup for you is, but I will say this.
If you go with the irons, never drive the same car on track with PCCBs. You’ll regret your decision. Perhaps forever.
I've done both on 991 3rs's. I still don't quite like the initial "bite" the pccbs have on track and prefer irons. But I'm being really picky and the difference in feel between iron and pccb is getting negligible on track these days. On the street, I LOVE the bite of pccb over irons. And love the lack of dust.
There are arguments on both sides of the ledger and I order/buy cars with steel or pccb. On a true DD car that isn't washed most of the time after it's driven, the cleanliness of pccb is more important for me on dd-like car. For a fun occasional toy and/or a track heavy car, it's a toss-up for me.
Check out the tread I started back in 2015... Lots of valuable data from good contributors.
I dont see PCCB being a problem on a car that wont be tracked hard.
I had PCCB on my .1 GT3 and really liked it (no dust, look and lightness feel) but I did get a rock between caliper & wheel once... damaging the wheel.
I would get PCCB measured on a used car before buying.
People complain about the maintenance costs. Tracking a couple times a year you will need to drive the car to over 50K+ miles. Really are there that many people on this forum that keep their cars that long? and if you do are you tracking them? because then it is closer to 100K.
Buy PCCB, and when you do and drive a car with them you will never go back.
I've avoided PCCB religiously. Only reason is fear of the maintenance costs. Thinking I'm being too picky maybe. Currently searching for a low spec used .2 GT3. Car will be a weekend car, driven to track days and probably tracked two or three times per year. (I do most of my track time in the Radical). I've nearly talked myself in to being agnostic to PCCB other than the initial purchase price. Or should I go back to my iron-only POV?
Opinions please.
Thanks,
Tim
I sounds like you WANT them, just rationalizing why you won't get them. In the above scenario you painted, then I'd say get them. Yes, they will cost more initially and to replace but will last a long time with your use, and lower dust may make up for the street squeal.
That's me trying to think like you as I understand your post. Me, personally, I don't want PCCB's. They cost too much for little added benefit, I track my car a lot, and it's not much more to wash the brake dust off after I get done removing all the melted rubber off the car front, windshield, fenders, etc. But, that's for me, and likely not for you. Get the PCCBs

I don't think the difference is just the bite of the PCCBs.
I think, for me anyway, the major difference is lower unsprung weight that contributes to different handling characteristics of the car and the confidence that whatever initial bite you had at the first turn on your first lap will still be there on that same first turn on your 10th lap in the same session. It's that latter confidence-inspiring feeling of the PCCBs with respect to brake fade that really makes the difference for me.
I had PCCBs on my GT4 and switched to Girodics from Clark. From a braking perspective I really didn't notice much of a difference For the last 1 1/2 years I went back to the PCCBs.
I recently switched back to a 15 GT3 with PCCBs. Since I'll only track the car once or twice a year along with a couple of leisurely Smokies GT trips per year I'll just stick with the PCCBs for now.
My PCCB squeak when NOT braking. Dealership took for a test ride, heard the squeak when NOT braking. I'm told this is normal as there is "play" in the rotors.
Had iron brakes on my first 5 - 911's. Always thought they were great. Then came the TTS which only came with PCCB. I was an instant convert for all the positive reasons above.
When time came to build a GT3T.... including PCCBs in my build was a no-brainer.
As mentioned above, on a used purchase it's wise to have PCCB rotors measured and inspected.

I’ve driven back to back GT3 with iron and RS with PCCB. I’ve also driven back to back iron brakes vs the light AP BBK on same model GT3. In all cases I haven’t noticed any handling differences from the weight differences. But I did like the feel of the PCCB, as well as the OEM iron setup.
I track enough that I am happy to not have to worry about damaging discs or having to replace them within 2 years, so I spec iron.
For someone who tracks their car heavily it’s a no brainer to just get irons; rotors are a consumable item and will need replacing frequently if you are really driving hard. Best to keep costs low. However, if no tracking then by all means get pccb. Not just my opinion, AP said this as well in an interview.
