Anyone ever use the wheel spacers to get the tires away from suspension. I have a 2000 Sport with the new and bigger tires on the jeep the inside of the tires is very close, even after I moved the track Bar. Are these spacer OK on the street (street driving) and off road (rugged and unbreakable), and Is there a size I should stay away from. I believe if I get 1 or 1.5 in spacer it would be far enough from the suspensin. Thanks in advance. :?:
