It should be perfect, the only thing it likely wont clear is the booster, but that wont be the fault of the offset, that will be the fault of the width.
a 7 inch wide wheel will tuck like crazy with a 5.5 backspace, which means any wheel you get will need a 2.5 FRONTSPACE. (2.5 + 5.5 =8, a 7 inch wide wheel is actually 8 inches lip to lip because of the extra 1/2 inch on each side for the lips)
So if we want an 8 inch wide wheel, we will still need 2.5 forntspace, an 8 inch wheel + 1 inch for lips is 9 - 2.5 frontspace = 6.5 backspace.
6.5 backspace on an 8 inch wide wheel is 9 / 2 = 4.5 centerline, - 6.5 backspace = 2 inch positive offset, 2 inches is ~50mm, so for an 8 inch wide wheel you need +50 offset.
So I'm probably wrong.
