My custom backspace is 5.25” but be advised there are two different widths of 12-bolts. I believe the standard bs was 4.5” for my wheels, so that would have put them into the outer wheel wells with a 5” drop. Without being lowered the standard bs would bolt right in, but that would have them sticking out a bit from the truck.
