There have been discussions regarding carbon wheels and the un-sprung weight savings that can be realized (each wheel would weigh 12-15 lb). As these wheels will need to be custom built to for our cars (or any car), a group buy could significantly reduce the costs (setup expenses spread over multiple wheel sets). Initial research indicates a cost of $6-8k for a wheel set, but the group buy might reduce it below $6k. To do this, we would first need to come to a consensus regarding style (and later size, offset, and center bore).
Please select your preference from the wheels below (keeping in mind that we will probably select a center bore to fit a standard Jag center cap). Please DO NOT VOTE, if you are not serious about a set of CF wheels in this price range
Are these CF-look, or actual CF? If actual, how are they going to survive first pothole?
They can't weigh in the 12-15lb range unless they are CF through and through. These will result in a total unsprung weight savings of close to 80 lbs over the 20" wheel options offered by Jag.
Not much more fragile than alloy wheels (if any).... and that's also why there's wheel insurance.
I would suggest we all agree to the 20" size as that will accommodate all of the brake configurations (except maybe the ceramics). That would then point towards a 9" or 9.5" wide front wheel and a 10.5" or 11" wide rear. If we find a suitable wheel at an acceptable price, we can then start negotiating the details such as width, offset and cap bore.
I'd vote for 20x11" out back if everyone is agreeable. From what I see, there's plenty of room back there.
Agreed, I believe the right answer would be to increase width by .5" front and rear and reduce the offsets by 9mm. That would put the wheel face exactly where the OEM wheels are with a 15 mm spacer. This actually would leave an additional 3 mm clearance on the inboard side of the tire even with the wider wheels.

Right on, I'm with you guys on increasing front and rear width. Since we're having these custom made, think the following would be about ideal, right?
20x11 offset 22mm: same inner and extends 12mm
20x9.5 offset 39mm: same inner and extends 12mm

Double check your numbers (remember, the additional width affects offset). Those offsets will yield a 22mm extension which likely to interfere with the fender lip.
For a 10mm extension the offset should be 34mm rear and 51mm front.
I would propose a 15mm extension which I am currently running (with a 1.5"drop) with no tire rub under any conditions: 29mm offset rear, 46mm offset front).
I would suggest that we have the wheel fabricator confirm the right offsets to ensure the desired extension.

Yes, my agreement is with an offset that produces the same result as adding 15mm spacers to the OEM wheel.
Ok...after much searching and discussions, this is the best I could come up with:
1. Except for ESE, none of the other CF wheel distributors were willing to custom size our wheels with less than about 40-50 wheel sets on the line.
2. ESE is willing to build the ESE-1 (option #2) to our specifications with a 5 set minimum buy for $7200/set plus $75/wheel to custom size the center cap hole for the Jag cap. (Their standard hole is sized for a Porsche cap or their own)
3. They are willing to custom engineer and design a wheel similar to options 4&5 for a $48,500 setup fee plus the same pricing per set as the ESE-1s. Might be worth it if we had interest from 30-40 people, but unlikely to occur.
So at this point it's option 2 at about 14# each or we move on to a group buy on forged wheels at about 20# each.
Who is interested in moving forward with the ESE-1s?

Group Buy?: Carbon Fiber Wheels
