What size spacer?
 

Just put some new wheels with lowering springs on the Z, and the fitment looks great, but the more I look at it, I think I could use a spacer in the back to bring the rear wheels flush. It looks like the bottom of the wheel is more flush than the top (camber). So two Questions:

-Should I install something to lessen the camber? (it doesn't need the camber to fit

-What's the easiest way to measure what size spacer I will need to get flush?

I used the search function, but couldn't find the answers to these two questions . ..
Thanks

Need information on wheel sizes and offsets to answer this question.

You could always use a ruler.

20 inch wheels, +35 offset, 305/25 tire

20x11 wheel

Straight edge, level. Put the straight edge up against the fender. Plumb us ing the level. Measure the distance from the straight edge to the tire.

Makes sense.... Thanks man.... How about the camber adjustment? Worth it to do? If not, should I make measure to make the top of the wheel flush or bottom?
