Yeah, I knew you were in Canada, LOL, my post should have read:
"according to Infiniti's US website it isn't available in the US."

 

The 19" wheels will fill up the wheelwell space a little more. I wouldn't go any larger than 19" wheels on the sedan.

 

19" wheels won't fill out the wheelwell more because they are the same diameter as OEM (or at least should be). Sorry to be so picky... but surprisingly there are people out there that think you can increase the outside diameter of the wheel and everything will still be ok.

However, larger rims do give the appearance of the overall wheel being larger. The only way to truly fill in the gap is to lower the car -- even as little as an inch will make a big difference and camber should still be able to be brought back within spec.

 

here's what it should look like...

 

What that doesn't show, and particulary the slammed photo does not, is how tucked in the stock wheels are. Every time I see a straight from the side shot with 17" stockers I forget how damn old fogey they looked in real life cos they're tucked so far under. A spacer would help a lot.

If I had seen that slammed photo before I invested in rims I may have done just that.
