like most of the sifu's said.. u'll need widebody..
just to share, i am running 18x9 +22.. having problem with rubbing on stock fenders even after rolling the rear fenders when rear seats are occupied.
so perhaps you would want to consider again if you're going for anything more and if you carry a full load most of the time.. then again it differs slightly from rim to rim but in this aspect a little is alot ;)
Gd luck in your search for your dream wheels bro.. trust me its worth the search :)
