Long story short, bought some wheels from a buddy with a G35. Swapped them on, ABS, Brake, VDC OFF, etc. lights came on. Found out the hard way the Z likes a slightly shorter tire on the rear than the front. I used this chart to try to matchup the correct tires before i purchase new fronts:

So before I go through this again, I just want some confirmation that setup will work on my car without screwing with the sensors.
