Minus 1" in the big picture, in my profile picture it is neutral height. 275/60/15 tire with an 8" rim and it's been a while but I think 4.5" back spacing with a .5" per side narrowed Strange S60 from Doctor Diff. I have put the same tire with a 10" wheel from my Belvedere under it with, again not real sure.....5" or 5.5" back spacing and it fit great too.......actually looked a little better in my opinion.
