The 21 inch wheel has a circumference of 66". Multiply that by its width (9.5" I think for the back) and you get a surface area of 627.
Take into account that there's less spoke material required to make the 19" than the 21" and the fact that they Corvette wheels are forged (lighter), and I find it hard to believe the 19's have "way more mass" than the 21's.
Just my .02
But back to the thread topic, cars these days are being made with larger wheel wells, so require larger wheels to fill them up. This somewhat hides the proportionality imbalance of a 22" wheel to a relatively small 2-door car, which I think is a shame. The 18's on the GS concept don't really fill the wells, so I'm thinking some lightweight forged 19's should work just fine.

Nice and I would not argue with that. I had in my head the Z06 wheels which are 2 inches wider. Whenever I think vette that is what I picture (my bad). Also "way more" was exagurated. Thanks for the breakdown! I still don't understand why the feel to get larger wheel to fill wheel well. Whatever happen to the profile of the tire. The 20's are a pretty descent profile, but the 19's or even 18's with a little larger profile still would fill the wheel wells IMO. I agree the stock 18's doesn't work very well, but I a sure there would be a better package of tire and wheel in the 18 in category that would look just fine. The koni challenge camaro has 18's on it, and I think it looks good, and you could go with a larger profile tire if you want wells filled and I think that setup might just look pretty damn good! Just a thought!
