Wheel fitment
 

Guys, I'm looking at getting the Vossen CV3's next spring as fall/winter is upon us. Anyway, I know that I don't want to get the staggered wheel set as I would like to be able to rotate them. I would like to get the 20's but have no idea what size tire to prevent rub. I haven't lowered it or anything and really haven't looked at due to our $#!tty roads here in TN. Suggestions fellow Z owners?

Considering your stock wheels are staggered, Id say start with researching more information about sizes and offsets. Educate yourself. There is a million different ways, reason and opinions on modding cars. Id say if your roads are garbage, then stay stock. Just my $.02

The staggered fitment is definitely recommended.
We can build a CV3 20x9 +15 20x10.5 +15 set for the Z that fits flush and well on the car.

Its impossible to fit a square setup flush on the Z without running spacers or staggering the offsets.
You could run the 20x9 +15 all around, with a 20mm spacer in the rear.
This would give you a square setup and the ability to rotate your tires.

I actually found an old thread where guys talked about their current wheel setups with details. Might just go ahead and stick with the staggered set up. Thanks for the info though!
