Why not more carbon fiber for weight loss.

In any case there is an issue of using scrap carbon fiber versus sheet carbon fiber.
That SGL company has really been in the news

Halltech started in October 1999, and was engaged on the Steve Merekov website, just prior to the Corvetteforum.com.

Lol! I think you have earned the right to state your opinion. You have one of the baddest Z06's on the planet.
My biggest problem with the base C7 and C7 Z06 is too much weight.
I wish GM would had you guys do some "consulting" on the C7 base and Z06, and they would have came out better and lighter.

Didn't seem to matter on the C6Z06.
To answer your question, we sell our carbon fiber hand made rear quarters for $900 each ready to paint. The mold was taken off the stock SMC parts. Rear Deck and Lexan window from Katech $2999; Roof and B-pillar from Halltech $1900; GM can make these parts much cheaper than we can.
Going to front carbon fenders would increase the cost maybe $800, so if that breaks your bank, you could stick with the base car, or GM could have carbon fiber options, like they do with the dash.
The base Z06 without the Z07 option will be around $90,000, and just over $100 with the Z07 package (guess)

Just on the subject of light weight wheels here are some wheel specs:
Volk TE37 (for the C6 Z06)
18 x 9.5, 35mm, 19 pounds weight
19 x 12, 57mm, 23 pounds weight
The Volk forged wheels are famous for both light weight and strength. And then the TE37 has a thick spoke look to it. The other popular Volk wheel models are the CE28N and the RE30.
BBS RS-GT (for the C6 base model)
18 x 9, 54mm, 21 pounds
19 x 10.5, 75mm, 23.5 pounds
.

The Sesto Elemento says that it has an integral carbon fiber bodyshell in forged composite. (Well, I would want the bodywork to be separate from the chassis for the purpose of replacement after smaller crashes.)

What's neat about this technology is that you can orient fibers for optimal performance. And since one can program the stitch head, there is near zero waste. A lot different than typical carbon fiber that most people know, where it is a fabric that is trimmed and fibers are typically 0/90.

those c6z are with option, base is still/well was 73 I believe...so full optioned c7Z bellow 100k (like 99998? lol) would make the new Z06 base around 75 I think...even at 79, Z07 is probably 10k (8 for brakes and 4 for all the carbon stuff), figure the other 10k to go to 100 are interior options...

Were the fenders on the C6 ZO6/ZO7 carbon fiber? If I am not mistaken, they were. If so, I think the OP has a valid point.
I also agree that we WILL see a C7 ZR1 sometime down the line. They may not call it a "ZR1" but it would be silly to think that we will not get a superior car down the line. We are in year two of the C7 generation and we already have a ZO6. I can envision carbon fiber everything, L88 (~700+hp), polycarbonate quarter and rear windows, etc. Think Porsche GT3/2 vs Porsche GT3/2 RS...A ZO6 "RS" if you will. It will come. If the economy doesn't go to total ****, you count on a superior model. It is not a matter of "if," but rather "when."

Plasan does have the molds for the Stingray. They make the hoods/roofs with a new technology called Pressure Press technology that makes the hoods in 20 minutes!!

Who knows, maybe by next year the fenders and other panels will be available in this same technology.

track optimized wheels dont have to last 100,000 miles of potholed roads and curbs, otherwise more OEM sports wheels would be nearer 20 lbs to save fuel and reduce unsprung weight, but cost accountants and sales execs have to present a realistic business case to mgmt for every model variant .

Yes, from day one in 2005. The C6Z06 came with carbon fiber front fenders. If I remember correctly, the pitch was that the primer and paint was heavier than the fenders.

There is no reason why their technology cannot be applied to fenders and these other panels. GM, for whatever reason, in addition to the hood and the roof being high CG, selected the applications for Stingray.
As I posted earlier, unless there is a capital investment made, Plasan is probably close to being capacity constrained in their Walker, Michigan facility.
Your original point about mass efficiency is well taken. As GM is trying to commercialize the vehicle at a low (relatively speaking) price point, they need to constantly balance what technologies give the best value.
We'll just all have to see, later this year, what the price point truly will be, and what technologies are used on the panels unique to the Z06.

And I think this is a good thread to illustrate that GM did cut costs to achieve a very accessible base price. Examples like this, the LT4 not being hand built, etc will make it possible for GM to release their biggest performance bargain yet.

They are doing everything they can to keep this car priced under 100k.

I agree with Jim -
I would have suspected more CF on the C7 Z06. I really like the car, but thought they would want to be as light as possible with that new LT4.

Also, the cheapest aftermarket wheels are often the heaviest wheels and like OEM wheels.
The Volk TE37 itself is a very stout looking wheel with wide and thick spokes. Even the rim seems thick

my point about real world durabilty stands, or you would see OEM full carbon fiber wheels now on coming million dollar LaFerrari, P1 or 918 Spyder
bending a wheel on a pothole is different than cracking a carbon fiber wheel, esp in these appliactions where the sidewalls are like rubber bands and the speeds are in the high 100s on the Autobahn.
