15x8 0 is not quite right for either end of an ae86.
I bought some wheels that had 215s on them, they were 15x7 staggered fins, I think zero front and plus 13 rear. I have a set of 8s but they are -6/-8 offset southernways and the fronts fit nicely with a good flush look on a stock front flare and xt130 lca but the rears were 20mm out of the arches each side. I have mx13 diff so maybe would be 16mm wider than the arches per side on a stock diff.
