I actually heard about that in a Motor Trend video on Youtube, where they pitted the C7 Z06 against the GT-R Nismo. I did hear about them making the center part of the black thing translucent for rearward visibility, but I think I didn't hear quite well that the black thing was carbon fibre XD but yeah, I didn't know translucent carbon fibre was possible. I remember the GT-R Nismo beating the C7 Z06, even though the Vette was the better spec-wise.
And while the extensive use of carbon fibre throughout the car is ingenious (Carbon fibre suspension is enough for me to give this car a 'Cool' rating), I just don't like the look of the carbon fibre splitter and spoiler. So it still stays Seriously Uncool for me.
