The wheels on the yellow one at 18x8.5 +35...pretty sure.

I'd just stick with 18x9+29. Its aggressive, but it'll fit the stock fenders. If you go much more aggressive (18x9.5) your going to have to mod your fenders alot/widebody.

I have 18x9.5+25 in the front, and it rubs at times with stock/unrolled fenders.

 

18x9 +22 would fit fine in front. The rear would need some rolling.

I fit 18x9.5 +15 on my car with concave spoke on stock fenders for the JDM look. It just depends how much you want to do to make it look the way you want - the more extreme, the more modification required.

 

Lets not forget about what size tires you run ??

 

I'm running 235/40 because of the +15. It is fine for street driving and show. For track, I wouldn't use this set up.

With a +22 on a 18x9 you will have no problem running up to a 255 with fender rolling. That is plenty big for a rim that width.

Going back to the original post, the 18x9 +29 offset on the Advan wheels is pretty good. It will give you the GTR spoke and minimal fitment issues.
