I just found these pictures that were from one of the vendors at the Corvette Musuem in BG last year. These are real carbon fiber wheel barrels with forged aluminum centers. If I remember correctly they had a price tag of $10k USD for a set of 4. I picked one of the rear rims up for a C7 Z06, they were amzingly light, you could pick them up with one finger. Not a cheap wheel, but the unsprung weight is unbelievable. This would be a great addition for all the carbon fiber addicted guys.
