Different wheel width
 

So ive been thinking of getting a 370z soon and the first thing i was going to get for it is wheels. I know the z with a sports package comes with 9 inch wide wheels in the front and 10 in the back. Is there any pros or cons of having thinner wheels in the front than in the back or should i just go with 10 inch all around?

same size all the way around is for AWD its good to have staggered on RWD but keep the same difference if you go 10 rear go 9 front if you go 10.5 rear go 9.5 front

any idea why robispec 370z uses 10.5 inch all around than? whats the benefit of having it staggered on a rwd?

If you are an advanced track driver like Rob the square setup makes the car easier to rotate without having to resort to stiff rear anti-rollbars, and the car feels more balanced overall.

The staggered setup builds in a certain amount of understeer which makes it a little easier to drive, but the downside is if you do want the rear to rotate it can be harder to make the back end come around without resorting to aggressive driving tactics.
