What prompted me to post (earlier) was the implication that some of the posted offset info was wrong (possibly mine being one of them.) So I spoke up mainly to draw attention to the fact that I knew my info (+12mm) was correct.
Also, just an FYI for newbie wheel shoppers; check out hub (bore) dimensions(diameter) before buying as this has burned previous VX'ers in the past! (I do not recall the actual dimension for our hubs.)
Yours were never in question... only the "0" or "Negative" offset wheels that look "normal" 0 or negative would stick out far no matter how you slice it
I believe our center bore is 100mm, but most wheels (mine included) come in a 108mm center bore. (for GMs)
