Corvette Performance - Help with .......

What are the widerst tires that can fit on a 2000 Coupe, and what tranny/differential fluid are you a4 guys running?

I. Would say 325 on the back safely and 255 on the front. If you go wider then that on the front it's more prone to hydroplane. I go on a friends word on his z06. And he work at a tire shop.
Just my 02 cents
hope that helps
