awesome thank u guys soo much! One last question would I need the 40/35 in front n back? Or just back? N true. Oem's look more classy but I just want bigger

 

LOL again depends on your wheel combo and set up....if your going staggered i would do 40 front and 35 rear (being if you got 20s) with 19"s I would do 40's....35 is very very thin and god forbid you hit a pothole and crack a rim....

 

Haha im soo frustrated! With every new answer I get comes 5 more questions. You guys must hate me.
Let me see if i got this...
SO if i Get 20 inch rims 20x8.5 (all around for all four wheels) then i need "40's all round?

And if i get 20x8.5 (for two in front) and 20x10 (for two wheels in back) then i need 40 in front and 35 in back?

Somehow i think this is still terribly wrong.
Truthfully though is there any website i can go and read about all this?
I tried finding one but none are too helpful

 

btw i took one posters advicce and contacted the seller ...but all he replied was that "i have a set to fit the infiniti g37" so i don't know what to believe

 

you can get a single piece wheels for the no lip but concave look..
