Need an answer that I can understand.

LONDON2012

I don't really understand how to get a flush look with wheel offsets. I do not want to use spacers. Ive asked a couple of vendors, but they haven't explained it. So i will ask you guys.

This is what i want...19 Advan RS wheels and a flush look on the 370z. My understanding is that I can get 19X9 and 19x10 wheels in the RS. I don't know if I should stagger or go 10 all around. The offsets provided by one vendor for these wheels was Front 19x9.0 +22 and rear 19x10.0 +15. What i don't understand is how those can be identical to the offsets recommended to me when I had a 350z. From my research, I've found that stock 350z wheels were Front 18x8 Offset: +30mm, Rear 18x8.5 Offset: +33mm. and the stock sport wheels on the 370z are front 19 x 9 +47 19 x 10 +30.

Basically my questions are: will the recommendation give me a flush look? How can they be flush on both the 350z and the 370z when these vehicles have different stock offsets?

Thank you.
