have the 350Z track wheels 18x8r and 18x8.5r with 30 & 33 offest respectivley..
sedans offset is 45, will the Zs offset create any undue stress on any of the suspension in the long term?

 

No, but you will likely rub in the rear

 

I wouldn't worry about it.
No rubbing here.

 

people rub with the oem 19s and a drop, and they are the same size and offsets, so i would think there would be the same issues

 

grumpy g, Do you have pics of your sedan with the rims on? Just wondering if the track rims you are talking about is the same as what some call the 350z anniversary wheels?? (5 spoke w/no divots)

It would greatly be appreciated, as I am looking to get off of these ugly chrome wheels the last owner placed on my car... Also these should clear factory brembos correct?
