Does anybody know if I have to roll fender to put 20x10.5 vossen cv4 all the way around and how does It ride any rubbing or anything or problems

 

offset? tire sizes? do you have an X or RWD?

 

Its rwd the g35s model and I believe it +25 and I'm not sure on the tires I don't want skinny tires I want the thickess tires I can get

 

Those wheels will not fit in the conventional sense, however you can make anything fit if you have enough money.

 

Are you lowered?

 

Ya on ebiach pro kit sprinfs

 

Keep in mind your OEM setup is 7.5" +45, you're going 3" wider (so it'll extend 1.5" further) and 20mm further out w/ the offset, so you're looking at almost 2.5" extended out further from where you are. Unless you're going for the slam/stretch/camber you're going to have to pull the fenders. Here's a good calculator for fitment

i got 18X11.5 and 18X 12 hoping itll fit

 

I have 20x9.5 +35 in the front, and 20x10.5 +25 in the back, i had to do a pretty aggressive fender pull to fit the 10.5 but it fits now. The fronts are ok. Very minimal rubbing on mine

 

I have +27 all around. I can tell you it will not fit. Now, for our cars you can't roll the fenders. You have to pull them which i did and i am not happy with the job that the company did. After trying to work with them they just moved and did not take care of my situation and didn't care for the job. I got my fenders pulled out 3 maybe 4 inches to clear the wheels on my car.

 

Wow 3-4 inches? I got mine pulled maybe an inch and i have +25 with -4 camber and it just barley clears, but its beautiful.

 

Yeah mine was poking out an inch an a 1/2. I wanted enough room for clearance which i got.
