Hey guys. I'm set on purchasing new TE37's for my 07 g35x, I'm just not sure if i should go w/18" or 19" 's. I do plan on running my car down the track a few times this year, and am not sure how much of a difference the diameter of the wheel will have. Also, whichever i choose, it will be 9.5" wide all around, and probably 3x offset. What is the best tire size to make them look flush? (I will be dropping my car on Eibach's soon) I know the least when it comes to wheels/tires, so go easy on me. Thank you in advance.

 

18x9 in the front and 18x10 in the rears with 245/50/18 and 275/50/18 i wouldnt know the offset. or 19x9 in the front and 19x10 in the rears with 245/45/19 and 275/45/19. but if you can squeeze 285 on the rears that would be great.
