Hey,
I'm new to the forum. I just put new 18s on my G37x sedan. Im look in on advice on how to give it a more aftermarket look. I didn't go with 20s as I drive a lot and didn't want to affect my ride or go through tires. I'm new to the whole car upgrading scene. So any feed back would be helpful.

Wheels: 18x8.5 +38
Tires: 225/50/18 this is what the tire guy said what comes OEM for 18s.
Thanks

mac , slap as many Decals on the rear windows and back corners as you can No joke - can be "artistic-cool" If 'n when you don't like anymore ya simply scrape off G 2/24/2018

Heres a picture of her. Should I go with 20's?

mac , yeah you could "fill" the wheel well a little more (diameter-wise) , I think NOW your wheels look "sunk-in" and a REAL punch woul be be wider rims + Super wide on the tires (watch clearance of course) , "Square Shoulder " tires always in my opinion look best yet the Big "Dognuts" will maybe clear better Sz. for Sz.

Going with 20's is all about preference but the larger the wheel the weirder it will look without a drop, IMO. The people who sold you the 225's for the new wheels "just because they are a factory size" don't seem to smart. I would have at least gone 245-40 all around at a minimum.
