I would think they were the same, but when I purchased my car the guy said something about the ZR's getting a smaller dia. rear wheel b/c it wouldn't fit(something to do with the top). I wanted to tell him that he is full of it b/c I've seen plenty of guys on here with 20's. I am about to purchase a used set of 20's from a coupe, just want to be sure they fit before I do.
Thanks!

The only difference is the Roadster's suspension sits slightly lower ... there's no wheel difference whatsoever.

 

Thanks! Now, if I order aftermarket springs will there be a diff in part #'s? I did a search, but couldn't find a concrete anwser

 

Don't think so... I put Nismo S Suspension on my ZR and its suppose to be only for the coupe.. I've had it on my car for over 2 years now and no problems..

 

Mind me asking what you payed for the nismo setup, and how much the drop is?
BTW: gorgeous car!
