OK, well, this is probably one of the more idiotic questions, but I gotta ask... if you put the bolted wheel-spacers on, is a wheel-alignment necessary? I'm kind of thinking that it probably isn't a must-do, but that I'll be better off doing so anyway. The reason being is that I don't see how it would necessarily throw off the alignment itself unless the surface it was being attached to (around the bolts) was uneven or if the product itself was not perfectly flat or not properly and evenly tightened. But beyond that, I can't see much need to do an alignment. I'm just trying to find out so I can factor in the cost of doing so...
