i was wondering if there was a big difference on stress points whith rims that have a wheel spacer with them compared to a offset wheel that doesnt have a wheel spacer

 

Stress point is the spacer itself, and your wheel studs. That and the money you spent on good spacers is what you would spend on steel wheels

 

everything will be more stressed in the front suspension,not just the studs,
the wider stance, weather from offset wheels or spacers, will put more pressure on shocks,balljoints, bearings, bushings, etc, the longer the line pivoting, the more pressure it puts on things holding/controlling it
