Well from what I've read it seems they're best kept for the road only, or maybe light track work also.
Feedback on the latest version seems to be quite positive so far, but maybe early days.
Positive issues would seem to be less unsprung weight, little brake dust, and no corrosion.
I doubt much of the cost will be recouped on selling, although if the latest version proves to be problem free, then maybe it could be a sought after option.
For what it's worth I've specced them on a new GT3 - road use only - after much reading up and deliberating, time will tell as they say.

I have them on my 05 GT3.
I've replaced three sets of discs on 2 x BoxsterS' and one 993.
I reckon they are absolutely fantastic --- after only 8000 miles (sorry).
But my GT3 is set-up on it's softest settngs for fast road work, and I love it.
PCCB's mean no worry about rusted on brakes, clean wheels, no disc rusting, fab braking and the best possible performance on B roads --- to me.
Coming as I do from a manufacturing background, my view is that there isn't anything made that the user can't break, somehow. Take a predominantly road car with PCCB's, add inexperience wannabe racers --- and Porsche were between a rock and a hard place.
Result, trouble, and the vociferous few were happy to try to pressurise Porsche into replaceing them --- time and time again ?
As they are with corrosion on the GT3RS alloy wheels.
The problem is that if the price of PCCB's is to fall, Porsche need volume. So I hope that the latest version perform well enough --- and that the market is becoming a little more educated.
P.S. As a fall back, fitting steels is not expensive.

ChrisW - There was a lot of issues with the first generation PCCB which Porsche promoted as the ultimate motorsport brake package so no wonder when they started to break up after a few trackdays the owners were disgruntled when Porsche refused to accept anything was wrong with them. If they were so perfect why did they bring out so soon an upgraded package?. Porsche also changed the promotional language, removing all reference to track use.
As for your reference to alloys I have a £5k Honda Accord motorway slag with perfect alloys.
I paid £55k for my Porsche and the wheel finish is the absolute pits in comparison - blistered, discoloured, milky.
If you are saying all the above is ok and acceptable you are, in my opinion, a plonker. And that is putting it politely.
I hope your discs last a lot longer than your steels did.... and going by the price of them you will need to do a lot more than 8000 miles to break even.

Done a search, but only posts about problems with these.
Given my use will be road only, and motorway / dual carriageway almost exclusively,
would this be 6k down the drain on any 997, including the turbo?

PCCBs are quite an expensive option, and very expensive to replace - should the need arise.
About a year ago I did a lot of research, hoping to prove that they weren't essential, but most of the evidence stacked up in their favour including some very valuable endorsements. So, I spec'd them on my 997 GT3 and I'm now a complete convert. The claimed benefits are significant and detectable. However, I haven't driven a new GT3 on steels so I can't can't say how much better the PCCBs might be.
I'd spec them on any new Porsche but I don't think the market has yet understood the benefits, so it is questionable whether much of the initial cost would be recoverable at resale. The exception is likely to be the GT3. The GT3 was designed and developed around the latest (3rd) generation PCCBs, and over 60% of new GT3s are being ordered with them, so it is likely that there will be a healthy secondary market for PCCB equipped GT3s.
Of course the long term life cycle is still unproven, especially on track, but in road use mine produce no dust on the wheels, which would indicate a low wear rate.
