Wheel sizing help

FLDave

Hi All!

Copying this from the new owner thread since i got no reply there. I just picked up a 2011 370z base model and I'm looking at a staggered set of 19" Avant Garde M310 Wheels. But before I buy, I want to make sure they'll fit with the stock setup, if they'll be flush, etc. I've been searching and reading threads for two days, and I definitely feel a little smarter, but can't get a comfortable feeling that I know what I'm doing yet.

Here's what I'm looking at:

19x9.5" fronts / 19x11" rears
Offset: et 20 fronts and et 18 rears

I know i've seen plenty of posts on here with 11" rears, but I don't know if something had to be done to make them fit. Any help is greatly appreciated!
