Hey guys I've been searching and been on Google to find out what size wheels I can run for my 2011 G37x coupe without messing up the AWD system. I was looking at Avant Garde M310 but want something like the type of the wheel but more concave? I prefer going 19s wheels specs like the 370z 19" rays engineering ones.

I'm on stock 18s and the width of the wheels are pretty thin doesn't look right from behind lol.

If anyone could help, would be appreciated!

 

Those 310s are a nice concave setup, VMRs have a deep concave look but don't think they have our bolt spacing. Do you want a square or staggered set? You could probably squeeze a 19x9.5 square setup at offset around +30 running 245/40/19s all around or a 19x8.5 +25 w/ 245/40/19 and 19x9.5 +30 w/ 285/35/19 staggered for AWD compatibility.

 

Probably a staggered set.

 

I see they make an 11" wheel, so you could go 9.5 +30 w/ 245/40/19
and 11 +40 285/35/19 for a aggressive look, or the sizes I previously listed for a bit milder set.
The coupe experts would be better for exact offsets, these will work but may not be as flush as you want

 

I may go with the one you listed previously.

No one with coupes isn't helping out lol.

 

Would I be able to run 19x9 front and 19x10 rear?

 

Yes

 

Sweet. What about the offsets

Could I run 19x9 +35 in front and 19x10 +25 in rear??

 

Having an X you really "need" to have almost exact diameters front & rear so the tires you have to have for the best setup would be those 245/40/19 285/35/19, that said those will fit up just fine on those wheel sizes. The rear offset "should" be fine but I'd run that wheel in the tire calculator to be sure.
Here's the numbers based on your stock setup~
It looks like it will extend about 39 mm out from where you are now, I used a 8.5" +45 offset for your stock set, here's the calculator and not sure on your rim width but I entered 8.5", but the offset is correct for your X. If the 39mm is too much you can always go w/ the +38 and get spacers to flush it out.

Okay so then I can run 19x9 +35 offset all around and I'll be good? Also would 19x10 be any big difference?
