i have a 2002 wrangler ridding on 33x12.50x15 mickythompson mtz mounted on 10x15 wheels.im looking for a meaner stance to the jeep. And was woundering about adding a 1.5 0r 2" wheel spacers to the front or the rear but not both, are these things safe to run i've herd good and bad being it puts such a load on the factory studs and pre loads or applies more preasure on the bearings is this true ,i can see the strain on the front as far as streeing but not on the back ,any input on this ,i'm not having rubbing issues just looking for a different look for the jeep thats it ,thanks
