Definitely two camps regarding PCCB, those that don't have them and don't see them as good value or those that have them and wouldn't be without. Neither camp is wrong it's just what floats your boat I guess.
Having driven with them on a couple of cars on the road (AM V12VS) I couldn't really notice any difference but am sure that if you do track days then you would feel the benefit from their consistency and fade free performance.Edited by dreamcar on Monday 26th January 15:14
Hopefully the GT4 will be a more track orientated car and then I think more people will spec them.
You are right to say neither camp is wrong there just seems to be a much larger camp that will spec the comfort based items as they will possibly never feel the need to use the car hard enough for the PCCB's to be a benefit to them.
lets hope there are "NO comfort based items" to spec back in, the GT3 2nd hand market is pants if you want a motorsport spec car
80% being comfort seats !
if anyone specs sports seats in a GT4 I will personally call them a **** :-P
PCCB seems a daft option on this car also, it has standard f
k off big brakes and should weight sub 1300kg's
you had to spec PCCB on the 987 and 981 as the brakes are not that good, but on the 981 at least you can bolt on the 991 S calipers easy/cheap for about £1.2k
on the 987.2 you have to fit 996 GT3 front calipers and hubs etc to get them to fit and it's a lot more money to do that.
Any way only 9 days till spec release day.

Judging by the comments from those who have LOIs you might not have to call too many people ****s as most seem to want it to be a motorsport spec car80% being comfort seats !

Not sure how the Porsche warranty would stand up to going off spec like that.....not something I would contemplate. Even if you could put the 991 S calipers on you'd still need to change the discs as the 981 cast iron discs are 320mm, 991 has 350mm?PorscheGT4 said:

In your opinion it is daft, I spoke to a good few knowledgeable people before I spent £5k on them who told me the exact opposite. I reiterate, just because you wouldn't fit them doesn't make it daft for me - or others - to do so. k off big brakes and should weight sub 1300kg'sI wouldn't personally spend £2k on deviated stitching, a few strips of carbon (mainly because I don't like carbon), red (or grey) tachometer and bi-coloured seat belts, but I wouldn't call those that have daft.

I have a car with PCCB on it thanks, I know how good they are , but I also know if you want this car as a track car it's going to cost you about £15k in disks after 15 or so track days !!I wouldn't personally spend £2k on deviated stitching, a few strips of carbon (mainly because I don't like carbon), red (or grey) tachometer and bi-coloured seat belts, but I wouldn't call those that have daft.

not every one is fussed about Porsche warranty, and yes you have to fit the 350mm disks, but you can do that all in for about that price.PorscheGT4 said:
who and in what context ? not as a full on track car I can assure you of that.
No not as a full on track car. I was advised if I was planning on repeated track days NOT to opt for PCCB. Clearly I am dealing with an Internet "expert" here. No real point in continuing this debate. Suffice to say I satisfied myself having sought the opinions of various professional and knowledgeable sources including several who have had a great deal of experience with and without them before I made my decision. I am happy with that choice and have no regrets.Mermaid said:
What percentage of mileage will be track use for these cars.? & for the 7.2RS?
I don't know but if you, I or anyone else could answer that question we would be able to predict the lottery numbers aswell 
.How many miles any individual car would do and what percentage will be track. Depends on what you have in your stable and how you use that one vehicle or lots of vehicles.
Reading what peoples hopes are for the GT4 suggests that they want a more focused car which for many would be buckets, PCCB, harnesses and weight saving moves which would suggest a higher percentage of time on track.
As with everything on this thread that is only my thoughts on it, until a spec is announced you can speculate one way or another based on the various rumours/ insider knowledge.

I am fussed about a Porsche warranty and would never alter a car from what Porsche designed - in the belief they probably know a great deal more than I - or you - do.dreamcar said:

Most people are keen to keep the warranty intact, especially in the 1st 3 years.
I kept the Porsche warranty intact on all my cars until I sold them - in the case of my last Porsche, a 997/2 Carrera S, up to six years, not cheap but neither is almost anything on a Porsche if it breaks! Call it peace of mind!!PorscheGT4 said:

From what you say I too would classify it as a wet sump, however fancy it is divided from the crankcase. As far as I am concerned, practically speaking unless the tank is connected to the sump via a scavenge pump, and is physically sealed from it, it's wet sump. Baffle and divider plates don't count. (I appreciate my description was - deliberately- simplistic, but lots of posts have focused on the oil tank location as the defining argument)
Regarding "one dimensional" I assume you mean it warms the oil up when you want it to but doesn't cool it down, which, to some extent an external tank might. While that's true, any engine that we are likely to be concerned about will have an oil cooler which will perform that task. Without one an external tank does have an advantage (and was doubtless a consideration on early bikes).
And other cars with an integrated dry sump - no I can't think of one either - but I would think as much a cost issue as a design one.
really interesting stuff.... the s54b32 has one of these type of "internal systems" or what the ///M division call "semi dry sump" theirs a great picture of it here on page 10 of this detailed engine brief, is this the same type pf system the cayman uses??

manual, clubsport, bespoke suspension and big brakes.
I believe that if the PCCB option is the regular 350mm variety then I would be less inclined than if it was 380mm/410mm. If the 5k is spent to get bigger callipers and discs, I'm in but going by the 991 carrera S example, the standards are already 6 pot and offer only a token increase in disc diameter 340F/330R mm
