My PEC Day in the CGTS

I’ve arranged my PEC day for next week, asked for PCCB and x73 equipped CGTS and was told none available on that day. Does anyone know how many GTS’s are actually on the fleet at Silverstone?
For the purpose of comparison it wouldn't really matter if you tried Boxster or Cayman with / without PCCB - the cars drive very similarly and it's only the difference in the brakes you are interested in. When we did our half day experience in October they had Boxster GTS with and without PCCBMilnsey said:

Might be worth seeing if they have an S with PCCB, X73 and 20" wheels if you are just trying to see whether you want those two options. Should drive exactly like a CGTS apart from a little top end go.dreamcar said:

Depends on whether it really is just braking power you are interested in. While the cars are very similar, the general view is that the extra stiffness of the Cayman does make the handling and possibly the ride subtly different. Given that the differences PCCBs make in this area are likely to be subtle, you might be muddying the waters a bit basing your decision on a Boxster. Andrew911, I've gone round the houses on whether to order PCCBs on my BGTS. I've fallen into the steel camp primarily from a cost PoV as in every aspect they just seem to fall on the wrong side of VFM for me
1) bit too expensive initially for no major driving feel benefits. For me a £5k option should make the car night and day different, whereas I would suspect that most people couldn't tell the difference unless they drive one of each back to back.
2) theyre not the best option for the track unless you've got very deep pockets, which seems a bit pointless to me, and for the road the steels will more than do the job
3) replacement cost - should you be unlucky somehow and need to replace them with original items, it's of the order of £9k or so
4) come resale if selling privately, I think many people will actually be put off 981s with PCCBs as the risk of having to replace them will be a massive %tage of the value of the car in a few years time even if they go aftermarket. Even when I was looking for my GT3, I automatically discounted anything with PCCBs
On the plus side they do look great and fill the wheels very well.
Just too much of a whiff of form, style and prestige over useful function or me at that price and cost risk, even for Porsche

Thanks everyone so far for all the comments. Appreciate comments in favour for opting or not for PCCB's. I guess I really need to try these first before making any decision.
PCCB can be emotive! Very much a "marmite" subject - some wouldn't have them others wouldn't have anything else - there is no right or wrong.EVO did a test last month on steel versus carbon brakes with repeated 100 mph to 0 stops.
Haven't got the mag to hand but basically until the steels started to go off through heat, which would be presumably after hard track use, the stopping distances were virtually identical.
Once the steels got too much heat in them the they then took much longer to stop, think that was at about ten 100 to 0 stops. Very noticeable that the carbons were very consistent throughout although from memory the first couple of stops took longer than the steels which could have a bearing if predominant use is to be street based where you will take time to get the heat into them in the first place.
Would have expected one of the main benefits to be improved wheel control with the suspension having to deal with a lot less unsprung weight.

Yup, that's pretty much it^^. If the PCCBs behave like the jaguar ones in the test, you'll actually get a bit less braking power until they're properly hot. You'd have to be doing some pretty "vigorous" road driving to get the same heat into the discs as 2 back to back 100mph - 0 stops I imagineHaven't got the mag to hand but basically until the steels started to go off through heat, which would be presumably after hard track use, the stopping distances were virtually identical.
