I recently picked these uber rare 1st gen NT03's up and trying to decide if I should keep them or go for the 18" concave face 2nd gen NT03.
*Disclaimer* These were only test fitted and therefore my alignment specs and ride height are off and I would swap out the tires for smaller sizes if I keep the wheels.

I'm really liking the 17" look because the 18"s look a bit dub'ish to me but I love the concave face. I cannot choose help me s2ki.

17x8 +45 235/45 I will swap for 225/45
17x9 +43 275/40 '' '' 255/40






Side view:



18x9.5 +40 NT03+M w/245/40 all 4 corners.

 

i personally feel the concave ones a lot more

 

 

both are fantastic.. but yes the 18" is too big imo. go for the old gen and be different

 

18 concave for sure.

 

18 concave looks way better!

 

I actually have a set of NT03+m in 18s w/ 255 tires all around that i will be using in the summer for cruising, but for the track i have rpf1s.

I think you need to have less the 1/2 inch cap to pull of the 18s.
I have -3 camber front and -2.5 rear.

I was scared to get 18s because like everyone I thought they would look big, but i love them.

 

Really have any pictures of the 18"s? I would love to see more shots before I make a decision. As of right now I just feel the 17"s make the car look a little more "tough" and the 18"s look like bling.

 

if you don't want the 17's, I'd offer to buy the rear wheels off ya. mine are 17x8 +45 all around and i'm looking for those 17x9 rears

 

18 concave.
