Well somewhat decided. I have an 04 G35 coupe with the brembos...and I am going to upgrade to some black enkei Rpf1 or black 5zigen Fn01r-c...18X9.5 et 15 and 265/40/18 tires all around. I am looking into buying the Eibach Prokits soon after(I have had other springs and I always seem to go back to Eibach). do you guys think that will rub? should I go 275/40 in the back? will that throw the system outta whack? i just wanna do things write, since my main priority on this car is the handling. Any info would be great! thanx.

 

If I was you, I'd go bigger than 18's. They look to small and non-aggressive.

 

Your be fine. I would go with 19" tho.

 

You can only pull off 18's on a G35 if you get really aggressive fitments and slam the car. Those will look pretty good on the front, but you need 18x10.5 +15 for the rear.
