I responded to your other post, but figured I'll reply to this one as well since you're asking about the lip size here. FWIW, on a 10" wheel, you're not going to get a 5" or 6" lip with a flat face and +38 offset. The way that offset is calculated is from the backpad of the wheel which is the part that meets up with the hub to the center. So a 0 offset wheel would mean that the pad is exactly in the center of the wheel. There is a good amount of room between the face of the wheel and the pad so even if a 10" wheel had 0 offset, you're not going to get 5" of lip. That design looks like maybe 4" of lip on a 10" wheel because they're using a convex face which curves in some to give 4" of lip. You're not going to get 5" or 6" of lip unless you get like a 12" wheel or go deep into the negative offsets, both of which will cause your wheels to stick out like 2" from your fender.
That's the one thing about AC Forged I've noticed, they always advertise 5 or 6" of lip in all their eBay and CL ads which is impossible for a lot of fitments.
