My last cars 997TTs, GT4, 991.2 GTS Targa, GT3 and my incoming car (GT3) all PCCB, in between the TTs and GT4 I had a 991 4S on steels, as this was like a preregistered car I had no choice in the spec but the one thing I regretted was buying it without PCCB, saying that it was an immense car and the brakes were always spot on, it was me with the feeling that there was something missing.
The positives for me, better stopping power ( this will be argued), less dust, lighter, look better due to the way they fill the wheel (especially the fronts), less fade and they last a lot longer but for me in my mind they give me a bit more confidence.
Negatives, they are more expensive to buy and replace (although I never have), when they get wet, and I don't mean rain, a couple of times I have gone through deep puddled water ( slowly) and they seamed to take a lot longer to come back but never bothered me when cold as like most you drive fairly slowly keeping the revs down when you first go out to get your oil and everything else including your brakes warm and the last point you have to take care of them a bit more, following a spirited drive or track session cool them down before stopping and I never put my hand brake on, although sometimes it comes on by itself (?)
Like others, there is no wrong choice.
] If I get PCCBs, I would hope they'd last for as long as I kept the car.
