As far as I have been able to figure out, once you determine the backspacing, the offset is irrelevant when it comes to inside clearance. The backspace is the distance from the backside of the hub to the back lip of the wheel. The offset and backspace are directly related except offset is used to determine the distance off center the front of the flange is with respect to the center line of the wheel. The more positive the offset, the more inset the wheel will sit in the fender well and vise versa...Therefore the larger the backspace the more positive the offset will be.
I could be confused, but I'm sure someone will jump in if I have it wrong...

I just got new wheels yesterday on my 03 I'm running -6 offset and I had to trim the plastic valence with 315s but no rubbing on the leafs. Hope this helped.

if your looking for sick rims in black I would look at BMF or MHT. Those companies both have insane looking black rims
