I'm really thinking about getting the 370z oem wheels for my 2001 i30t. Just want to know would I run into any problems with the rear fitment since it has an offset?

Yes you would. You can put a front pair on the rear of your car. The 370z rears will stick out far.

They will fit...but you will have to run a slight stretch and roll your fenders

The stock tire size is no bueno I'll tell you right now.

If fitment is your goal don't try to get a pair of fronts for your complete setup.
The fronts are hellasunk unless you run spacers which I'm not a fan of.

Ok bro Imma have to find a look alike that will fit then

I don't think you got what I was saying. Get a staggered set instead of buying 4 fronts. Pretty sure you won't regret it. I love mine.

Yeah I love the fit of your wheels best stance hands down
