Do I think the wheels posted by UpFixenDerPorsche are of the same quality as a Koenigsegg unit? Not a chance, but it's a start.

Agreed, it's a start.
But then again, if you have unlimited funds, you don't care how many you damage with casual contact, or if it costs you the weekends $12 trophy.

I have a set of these on a 991 C4S.
The "ride quality" is improved noticeably over the stock wheels - specifically road shocks are damped better across the frequency range (I don't know what a real car engineer calls this). They also seem to have a different (preferable) behavior around changing lateral loads. These are in addition to what I expected from reduced unsprung weight.
In the Tudor USC, wheel weights have lower bounds which are above the CF weights.
They are happy to tell you specific weights (CarbonRev) for specific wheel sizes.
I like them a lot, and am looking forward to their CL version. I also like the people at CarbonRev that I have talked to.
I have zero data on cost curves, and in that blissfully ignorant state would think there isn't a reason for them not to come down in price with volume and competition. How's that for useless Internet opinionating?

I love it ... "reinventing the wheel"!
In bicycle frames CF has a shock-absorbing behavior that sets it apart from materials of equal or greater stiffness like steel alloys, aluminum and titanium. Maybe that property is inherent in CF and would be present to some extent in auto wheels as well ?

Do I detect a bit of put down going on?
I do make it a point not to post rubbish, hence the two links included in my opening post. Very informative.
This is from one of the links. Listen to the reply re Koenigsegg. No put down; just an explanation of the differences and the different manufacturing goals.
And FWIW I drool over Koenigsegg.

Nobody said it was rubbish.
But given a bottomless budget, in some show racing...sure..a CF wheel makes good fapware.
Club racing, forget it..wheels are just bumpers on the side of your car.

Leno seems a little unimpressed after a test drive. Wasn't there another carbon fiber rim manufacturer (Dymag?) that had a few breakages and then became defunct?
Different design though
What about just getting some BBS E85's?
It is intriguing though.

$15k wheels are perfectly fine on cars worth north of $100k. The average value of all the 928's left on the road is likely between $15 and $20k. We don't want to devolve into a community that spends as much or more on wheels and tires than our cars are worth.
I read an article the other day that claimed prices for CF will fall by 90% in the next few years. Making it feasable for the oem's to make far more components out of it. If that happens and CF wheel prices come down into the $4-5k per set range, I'll revisit the subject.
