The Centerline Revs are one of the few wheels out there with a 4" backspace and a 275/60 should really be run on an 8" rim or wider. (though I never really had a problem with them on 7" wheels) You will get a better footprint with a wider wheel.
In the past I ran a set of Weld Draglites with a 3.5" backspace and they stuck out too far for my taste. My car sits pretty low too and things get real tight when you do that.
Here are some pics of the new wheels, plan on lowering the rear about another 1/2" or so.
Fronts I ran 15 x 6 with 215/65's to get a faux "skinny" look without the hazards.
JDFAST you don't have to notch to put an 11' wheel if you want to run a 305 just nee the right backspace, ypu will have to trim the wheel molding.
