stock 2wd backspacing is 4.5"?
So comparing backspacing 4.5" --> 4" means the wheel will stick out .5" further due to backspacing
The wheel is also 1" wider so you have to add that in as well to make it 1.5" further out than stock wheels.
Or maybe this way might be clearer
7" wheel - 4.5" BS => outside of wheel is 2.5" from mounting surface
8" wheel - 4" BS => outside of wheel is 4" from mounting surface
4-2.5 = 1.5" further out
