I had asked Nissan directly (called corporate line) if using the NISMO spring kit on the Roadster was a problem and they just called me back and said that their engineers said that it won't work because of the extra 200 lbs. on the Roadster.

Another guy at one of the dealerships called a Nismo rep. and they said that it had been tested and is perfectly suitable.

Any additional info?

 

I have a roadster with the s-tune suspension. It works beautifully. No problems, issues or complaints.

 

Sweet. Thanks for the info. What is G-Attack anyway?

 

Same as s-tune, just a diff name.

 

the S-Tune was specifically designed for the coupe and the coupes weight and how the weight is distributed.

then again.. people put them on the G35's as well...

 

Thanks for all the great information. I guess the only thing that kinda worries me is that Nismo won't honor their warranty if I put the spring kit on my roadster.
