Ha! I take it that's "yes" to both questions. There's nothing simple, is there. As the Subaru tuners would say, stay stock, stay happy.Yes.
Anyway, I might go for it, with another check to see what's rubbing afterwards. Seems like 15x8 wheels with 4.75" backspace are less common, but Black Rock has some steel wheels in that spec with a decent load rating. Classic look too: Black Rock 997581247 Type 8 Series 997.
