What offset for steelies 15x8 with 26x10.15 et drags?
 

Guys, I am trying to pick up a set of 15x8 steel wheels and need to know what offset to get? I will be running a 26x10.15 et drag. Would a factory 15" wheel be better than buying a set of American racing ar 767's in 15x8? I searched but could not find the info I was looking for.
