Alright, I made my decision, gonna go with ADR Sterling. But ADR only goes to a 8.5" in the 19"s. I know a lot of people have put 20"s on the 350Z but some have had to roll the fenders. I'm guessing this because the fronts rub in a turn. I don't want to do any mods. What would happen if I went with 19"s in the front and 20"s in the back? Would I have a rub problem in the back? Would it effect ride, handling, speedo readings (I checked the speedo charts)? I'm thinking this setup might come off looking kind of cool.

Here is how it would setup:

245/35-19 Front (0.85 speedo error)
285/30-20 Back (0.19 speedo error)

 

Alright guys, I'm getting ready to pull the trigger today, can anyone help?

 

i've got 20's all around - no rubbing, no rolled fenders... (no drop either)

 

Won't that affect your traction control/ VDC?

 

no effect so far.... most of the time (unless its raining) my TCS is off anyways.... and as far as the VDC, i've got an Enthusiast so no VDC...
and there are a number of Z's with 20" wheels that i've seen...

 

How much difference on the speedo +/- are we talking about before it effects the VDC?

 

As long as your wheels are very close to the sizing of the stock wheels, you'll be fine., no TCS/VDC, etc. etc. to worry about. Pull the trigger!

 

Thanks for the imput guys, but the situation has changed. I ended up getting the 19" M Sport intstead. They don't go to 10" like I wanted but 9.5" is better than 8.5" the Sterling offered. And I got to tell you, the M Sport has a beautiful 2.5" lip on it. Plus I don't have to worry about the potential VDC problems.

Still trying to decide on the tires. How does this setup look?
