Speed Hunters Project Yankee at SEMA-- 1975 Dart Sport!
Wouldn't be hard to do with 315's, they'd stick out that far. With the 73+ disks you'd need an 18x11 with a +6 offset (6.2" backspace) and 315/30/18's. That should clear the frame, and they'd stick out about 1.6" further out than my 275's, so, more than an inch outside the fenders considering the clearance I have. I suppose you could just make it a nice even 0 offset and 6" backspace, that would put them out a good 2" past mine or about an inch and half past the fenders. Once you're out past the fenders it doesn't much matter anymore. If you ran a 68-70 B body rear axle you could run the same exact rims/tires in the back, that axle is pretty much square with a 73+ disk set up. Then you'd need a 2" wide flare (minimum).
Thing is, you'd have to cut the fenders too, similar to the Petty car (maybe not quite that much). No different than hanging the tires out past the quarters on the 70's street freak style drag cars. Once the tires are out past the body, you have to make sure the body and the tires never occupy the same space. So, you either raise the car up (like the street freaks with the crazy lifted rears), or you have to cut the body back. Whatever suspension travel you have is how much you'd need to cut out. So, that would mean cutting a couple inches of fender out all the way around the tire, to make sure the tire never hit the fender on turning or with suspension compression. Then you'd put the flares on, making sure the flares were wide enough to cover whatever amount of tire you added, plus clearance just like for the fenders.
Of course, with the flares you'd have nowhere to rest your foot...
Like the "Fish Tail" drift car, except you'd need bigger flares up front and you'd lose more fender than that
