Tires/Wheels

[Calgary351GT]

Hi all. I'm looking for new wheels and slicks for my car. Gonna go with M/T ET streets. (no luck with radials) and a set of Weld draglites.

I'm wondering what guys are running for sizes on their fox platforms.
How big can I go with the tires without cutting fenders and/or ground affects?
What rims sizes do I go with. Backspacing? Offsets?

I should stay as close to 26" as possible.
