hey guys !

Is someone as test to mount 18' on front and 19' on rear ?
A Z french owner want to put that on his car, cause his body kit is very low at the rear + he want to add a drag look...

 

the factory track and gt models on 06+ have them 18/19

 

Yep,

My stock GT has 18x9 ET 30 Front w/245/40/18 and 19x10 ET 30 Rear w/265/35/19

 

Yes but what does wheel diameter and rear body height have to do with one another?

 

doesnt the NISMO Z have 18`s in front and 19`s back??

 

Yes. Nismo and GT models have an 18/19 setup.

 

i'll confirm this comment to be correct

 

any benefit to driveability and handling over 18 or 19 all around? or just for the look?

 

Much more understeer with a staggered setup. Car walks around a bit and grabs a little funny on uneven surfaces, but you get used to it. Nothing bad enough that I would go back to a non-staggered setup. Front and rear sway bars may offset this, but I simply don't know (nor do I have first hand experience).

From purely a handling standpoint, I have to believe that the same size all around is going to be preferred.

EDIT: I just realize that wasn't exactly what you asked Everything else being equal, 18s are going to be less weight than 19s and give you a little more sidewall (a better ride to address your driveability concern). I would think that non-staggered 18s would be your best performance option, but that is based on a limited-experience opinion; I'm sure there are many others here with much more experience that can chime in.

 

I don't see any. There are racers who prefer a shorter sidewall, but no big deal for the street.

 

You are welcome.

 

lol ego much?
