Yeah, I bought two new 15x6 Cragar S/S's in December and I've been going back and forth as to whether to run 6's in back or 7's. I'll probably go with 6's and run smaller 70-series redline radials in front and larger 70's in back.
Hey, if the '50s guys can bring back the nostalgia hot rod look with big-n-little whitewalls/steelies then I think we musclecar guys could bring back a "nostalgia street machine" look. Besides, think of how fun it would be to have a street car with a healthy BB and 70-series tires out back?
