Sorry for the late response. I had it bored out to an even 68mm. Our hubs spec are 67.06mm. I believe I had the rears bored 1.5 inches deep and the fronts 1inch deep. I might have that backwards. It's been awhile. Just have them bore it deep enough just before the lip where the center cap holds onto and you should be good. Oh yeah, I should mention that the place I took mine to, (The Wheel Zone - Official Website) were bored on a lathe. YOU DO NOT WANT THEM BORED BY HAND. Let me know how it goes.

aberdeen wa sorry man that would be sweet

What state are you from? Im like 5 min from aderbeen md?

Sorry, That's all 4 wheels too.

Oh OK. I should mention that when I bored out my centers on the rims, I had a wheel shop do, I did not do it myself. It was done without the tires, on a lathe. Very precise, completely balanced and CHEAP. Here in San Diego, I paid a total of 80 bucks. That's with taking tires off, putting back on and rebalancing. So look around your area. I'm sure you can get it done right and at a fair price.

That is a lot of hardened metal to grind off. That alone sounds like more work than the other options. I don't think I heard of anyone doing this. If you were able to grind it off, what would hold your wheel bearing dust caps then? Just a thought

Center bore on a nissan i believe is 60.07. Our Toyotas are 67.06mm. You'll need to bore them out to get them to fit. You can also run 1/4" spacers If you don't want to bore the centers but you'll have to change the wheel studs to rear ones (they're longer).
Hope that helps,
Alex

Even though the 350z wheels are staggered, I'm running 215/35/R18's all around.
