I'm looking for some wheels in 19"/20" for my black '05 and I would like to see what everyone is running. It seems like most of the pics I see are of Z06's which are much more forgiving than a regular C6 of which wheel you choose. To me, the regular C6 just doesn't look right with a lot of wheels since you aren't able to get as wide a wheel as you can with the Z06, thus having a smaller lip. If you don't mind, post what your wheels are and maybe even the tire size you are running.
Here are some of my favorites as far as wheel design and stance goes.
