You know what it is Glock, these wheels can only do so much to this car. They both look good again today but then I'm looking at cars like yours with stock 20's polished, and they look just as good too. I think this particular wheel on the SHO can only do one thing....look good. Unless of course you paint it pink or green lol.
Since you did all the work already, I'd leave it copper for awhile until you get bored again. Actually, this was a good experiment as to what the capability is, of this wheel, on this car.
One thing though. People will know its you, and know when they got dusted by a red SHO with copper wheels. 'Officer it wasn't me....the other red sho with coppers just sped right by me'
