After I lift my jeep, I will likely have the stock wheels/tires on it for a few weeks, so I'll need to put the rear sway bars on the inside so that the wheels will fit. Can I leave them in this position? or should I change them once the tires go on?

 

You can run them like that while the stocks are on but I'd put them back once you install the others.

 

i think some people on here had to do the same until they got wheel spacers. but if your getting different wheels you would not have to worry about getting spacers. it would be fine though. some other people just flipped the bolts
