Crazy thought - say you buy some wheels (say... 17x10") that have a 22mm backspacing. Won't fit, sticks too far out, blah blah blah.
What's stopping someone from bringing the wheels to a machine shop, and having the back of the mounting face cut in something like... 13mm, to give you a 35mm offset?
