different size wheel in front then back...

I've seen it on Vette's, but personally I think I'll stick with the same diameter wheel all the way around. If you go with the same size rims and tires, then you've got the ability to rotate them. Not to mention that if I wanted any of my wheels to be lower profiled, I wouldn't want them to be in the back. It's already hard enough hooking up an overpowered RWD V8 car as it is. And that shorter side wall in the back is going to make it that much harder still.

….to each his own though.
