I don't care if 500 people you know use spacers without any issues. As soon as one wheel falls off, it is too dangerous. Spacers increse load on studs, bearings and other components by moving the position of the wheels mounting point. If one wheel comes off due to spacers and the car spins out of control killing a young family, possibly your family, do you consider that justifiably safe? If so you have rocks in your head.
