Can i put 19inch rays on my 06 g35x with stock suspension? I dont want to mess with my suspension.

Yes you can

The 19" rays from the '06 coupes look on sedans! There have been several sets for sale on our Marketplace under Private Classified 19" wheels. Good Luck & Enjoy the Ride!

Yes you can unless you want to lower the car later on 19 inch stock Rays will fit the car

Depends on what kind of fitment you want to achieve some like flush, static, or cambered out

The 19" Rays have different widths for front and rear, and usually run staggered size tires. Just make sure if you get them that the overall tire diameters wind up the same, or you will fry the transfer case.

^It's only a 1/2" / 2lb difference.

I know, I wasn't saying it because of the weight...the OP has an AWD model, so tire height needs to be the same front and rear. It he found a set with stock coupe tires, the rears are almost 3/4" taller (225/40 19 front vs. 245/40 19 rear). That will cause transfer case issues in the future if he just bolted them on as is.

Sedan 18" Rays clones achieve the look and ate 18x8.

It is possible to run a square setup on the OEM Rays. Which is why I pointed out the negligible stagger those wheels have.

I'm sure you can run the square set up. The difficulty you'll come across is piecing the set together.

Exactly. You need two pairs of fronts and have to run the same size tire. A little tricky to pull off

What if i get two pairs of rear? How would it be tricky to pull off?

It would be tricky because most people selling a set of Rays are not going to want to split them up and only sell 2. Most likely, you'd wind up buying 2 complete sets, and then selling off whatever ones you decide you don't want to run (either rears or fronts).
