In another thread lamaz pointed out to me that if you go to the official NISMO site off of the Nissan Z site and check the application for the S-Tune parts, they now all say compatible with the Z Roadster. Anyone remember seeing the disclaimers on the NISMO wheels and suspension about not been warrantied on Roadsters???? Had something to do with them not being tested yet on Roadsters. Well, it seems they have fixed THAT. Thanks to lamaz for pointing it out to me. It may be old news to some, but it was new news to me!!!!

 

Yeah, it's news to me, too, and thanks for posting. I remember those disclaimers and all the unnecessary phone calls and emails to make sure I could install nismo suspension.
I got so frustrated with the inconsistent responses, I said to hell w/ it, put in the nismo suspension and Enkei RPO3's in 18". I have had no problems with the s tune suspension and really like the more aggressive offsets on the RPO3's.
