My decision came down to weight, and if I was buying a "every day supercar" for an outrageous amount of $$, I wanted it to be the best Porsche could make it. The no dust thing was also a big plus.

Eventually I will upgrade the wheels, but I want substantial decrease in unsprung weight when I do it. Doesn't make sense to get PCCBs and then put on heavier wheels.

 

Couldn't agree more. Except for the point where you say that other 'waste' their money. All of these are personal decisions in the context that no one really 'needs' any of these add-ons (much less the car itself!).
But I will reiterate that it seems odd that people criticize the cost of the PCCB's but do spend huge amounts on other accouterments.
Whether it's overkill or not, next time I order a new one 997S Cab, I suspect I'll be checking the PCCB's upgrade box (unless I jump the gun and retro a set of Movit's).

 

not waste. (now I see waste was a term used by another poster)

But unsprung weight is many fold more important than sprung for car performance. I don't UNDERSTAND why people would put subtstantialy heavier wheels on a car such as this. Then again I don't understand or like many choices other people make, not do I expect them to agree with mine.

 

Better?

 

Speaking of a 928 GTS...

Porsche should build an updated version, instead of a Porsche-A-Rama thing.

 

You know, I was in my minds eye thinking that a stretched 928 would have been better than the panamaragafadarah is.

I was trying to make the points you cite, though I might have been clumsy in my approach. I don't recall what the function or formula(e) is, though recall reading about it, but you are very right about the value of minimizing unsprung weight. I suspect that PCCB's (or aftermarket carbon) + reduced weight wheels would have a remarkably positive impact on suspension dynamics. Think how much more accurate and lively a P-car (or any other sports car) would be if you could knock 10 lbs off of the axle lever arm.
20" wheels might look good to some, and for those who prioritize that, it's reason enough to buy them, but I believe that they typically outweigh stock and raise suspension inertia which is a bad thing.

 

As timeless and beautiful as the 928 series was and is (they look current and stunning even today), I'd leave the front-engine sports designs to Aston, Jaguar, Corvette or F-cars. Please, please just squeeze the GT3 or GT2 (!) engine in the Cayman, clean up the rear quarters a bit, and I am sooo there.
The steering feel of a Cayman, the sound and power of a GT2 or GT3, and the dynamics of a mid-engine. Where does the line form up?
I know you can get something like this done after-market, but it would be so right to get it from the white lab coats in Stuttgart.

 

I meant the 928 would be a better start point for a 4 door coupe design.

 

Ahh, I stand corrected then. And a stretched Cayman would really be a problem. Having an engine mounted between the first and second row of passengers would be a really bad idea

 

I think that's called a Hummer

 

After spending a long time this afternoon cleaning [four] ten spoke 18" wheels on my R32, I can hardly wait to have PCCB!

 

Being a self-proclaimed member of the unofficial OCD society (doubtlessly as many on this forum are as well), I actually evaluate wheel designs based on cleaning complexity (after weight - to be fair). On that front, the lobster-claw wheels really score horribly. What a pain to keep those clean.
Which is why the wheel design shown in this thread (depending on weight) is so compelling:

So yea, chalk up another value proposition for carbon (and simple and open wheel design).
