Hmmm ... with 18x8 45mm offset wheels, on a 2007 M (that is what you have, right?), you should not have had to use a spacer - it would only be needed for the 2003/2004 M45 with that offset value. The stock wheels for the 2006+ M have 47mm and 50mm offsets - info is in the stickies in this forum.

Spacers add rotating weight, alignment problems, potential for unbalancing, etc. Best to get correct offset wheels instead.

With incorrect offsets (using positive offsets as is typical for Nissan and Infiniti vehicles):
1. If the wheel sits too far out (too low an offset value), the tire could come under the fender and could touch the body on bumps (fwiw, I am not a fan of the stretch look!).
2. If the wheel sits too far in (too high an offset value), it could contact suspension components, particularly when turning - on the front wheels.
