15x8 w/ 4.5” BS on front/good handling size?

Sure. But he was taking about, and my comment is about centerlines

Aftermarket large bolt axles push out 1/4” per side wider than a stock A-body 8 3/4.

If you a have lower profile tire with not much bulge, a 4 7/8” backspacing rim might work with some thin spacers. It’s easier to adjust outwards then inwards.

Would need a particular tire for sure.
