Where'd you get the spacers? Looks bad ***!

http://www.ichibausa.com/350z03.html I went with the 15mm, but 20mm will work fine. I may end up going with the 20mm in the rear.

much better, looks really good! I got the same spacers. I had to go 20mm. My rim offset is made for pre 09 GTR models cause I bought them when I was in Japan.

I have 20mm on the rear now, plus 305/30/19 tires, really fills up the wheel well. I put 15mm on the front also, I'll have to get some new pics up. :-)

if i run the stock 19" rim tire setup can i just use 20mm rear and 15mm front spacers and the alignment be ok (no rubbing are turning problems) or do i need other parts ?

sorry for the noob question

No rubbing or turning problems with the 15/20 mm spacer combo whatsoever :-)
I've even went with wider tires then stock 305's and 255's and still no problems.
except for the front chin spoiler scrapping on driveways because the car is lower now. :-)
