The standard 18s/19 wheels will be desired, and maybe a 17 will fit easily on the rear of a C7 like it does on a C6.
And maybe the GTO spare tire for the front will still work too.
We shall see!

The GTO wheel will clear the 12.8 brakes but don't know if the calibers are larger creating a problem. How about just a factory high speed tire in a 195 wide size with a 6" wide wheel as a mini skinny? I think the rear brakes are over 13"? standard so the 17" wheel may not clear. Wonder if the base brakes from a C6 are going to fit the C7.
I want to add one more thing: No warranty and the price reduced by $3-5K. I'm going to tune it so will void the warranty anyway.
I suppose a looser converter than factory would be a little too much to ask but why not. Something like a 3200 Yank stall would be perfect along with the 3.15 gear.
I get 28-29 mpg running a steady 70 mph with my 3.15 gear. With my 2.73 I got 30-31. I'll sacrifice 2 mpg for that gear.
