Getting 19in niche wheels for my g37x.
Everything is stock. What wheels spacer size should I get for front and rear?

 

I'm not a wheel guy, but I've been on long enough to know who is. Jump into this thread and I'm sure Brad or one of the other vaults of knowledge will give you the best guidance. To lay some groundwork, you're going to need to provide the offsets for the wheels you're interested in. Best of luck.

 

lol @ vault of knowledge.
Wait until you get your wheels installed, then determine how much spacing you want. Spacers are easy to add later on and much better than wishing you got a few mm +/- than what you ordered.

 

Good advice, Brad. As always.

However, go look at the OP's thread history. To date, he's has 19 total posts, 14 of which are new threads with ambiguous titles and vacuous questions. I've fallen for it a few time too, before seeing the pattern.

Stop enabling him.
