The bolt circle is 5x4.5inches which equals to a 5x114.3mm and our Challengers are 5x115mm. So the question is, how do the spacers make the rims fit with no problems?

A spacer wouldn't fix the difference in bolt pattern size. But if it uses washers with an offset center, it would work. Personally I'd stick to rims that have the exact bolt pattern - never liked the idea of using offset washers.
