Saleen wheels to Fox question...

They rubbed on turns and bumps on my car. It's got lowered suspension though. You'll more than likely need to roll your fenders.
89's will definitely need fender mods to fit. I have that exact size of wheel with 245/40 and 275/40 and the car dropped 1.5 using Ford B springs. It doesn't rub on turns, but the back tire will scrape a bit if I go over an uneven road to quickly
