for a 22x9 you would need +70mm MINIMUM
likely "whatever offset you need" really means "if it can be done" because that is a lot of rim barrel to hang inside. The only wheel I know of that is even close to 9 inches wide with that much offset is a corvette wheel. If these are cast wheels, I am going to go ahead and guess when you tell them +70 there will be silence, then laughter, then a click, because that is outside the design limits of about every wheel made. Forcet about rubbing the caliper, on most wheels that would put the hub face outside the wheel!
if it were easy or cheap, everyone would be doing it.
