Hi guys. looking for spare lug nuts for my G37xS - 8.5" / 225/45/19 stock wheels.
1. Would you recommend buying OEM from the dealer or look for something on Rockauto?
2. Is the 17"/18"/19" OEM wheels lug nuts are the same?
Thanks

 

They are all the same, just be sure to get the "mag-style" sets, the ones w/ the tapered conical seats won't work
Here's a set on Ebay that would work

Thanks for the quick reply!
Does it make a difference if I track my car a few times a year?

 

No, just check torque prior to tracking if you aren't switching tires/wheels.
