70' C10 will this wheel offset look ok question?

[ur2noz]

Got a line on a nice set of 6lugs or my new c10. Need opinions as to if this will look ridiculous. He is my question though. They are 9.5" wide with a 4" offset. Now keep in mind this is a factor ride height truck but I plan on lowering it 1F3R in the future. I know stock wheels are 8" wide with a 4" offset. So in my quick thoughts these new wheels would push to the outside toward the fenders 1.5"? I can't remember if the entire width difference will be outward however. Seems I remember the difference being split and I would also have more rim on the inner side giving chance of rubbing on control arms, stop bumps yata yata. Just need some confirmation.

Thanks for your time guys,

Adam
