hi
i've putted the vossen vvs-cv3 on my g35 coupé.
the offsets are 10.5x20" offset 45. (rear)
now, the fitment is not great, too much inside.

i am thinking about to change it to 10.5x20" offset 15. (rear)
does they fit and flush?
(have original springs, and i dont want that the wheels scratch to the wheel box)

 

+15 will be a conservative, semi-flush.

That was my old set up.

 

and whats your new setup?

 

I used to run a 19 x 10.5 +18 on the rear when I was lowered on S-techs. It sat a hair inside the metal.

 

Hope vossen didn't tell you to get those offsets.

Switch to lowest offset available.

 

0 all around.

And this is good advice.

 

I'd say lower ur car & go +15 and roll ur fenders.

 

Just roll your fenders and you will be fine. You really should lower your car or else it is going to look strange though...
