I am very interested in getting a suspension for my Z soon. I have a question about the R tune and S tune suspension by nismo. I know the R tune is a Race tune suspension and the S tune is a Street/Sport tune suspension. But do you add the R tune to the S tune suspension to get the Race suspension or is it a totally different setup? Do you buy the R tune or the S tune? I have searched on it and have not found anything on either except reviews on the S tune.

 

I don't think anyone knows much about any of the R-tune specifics just yet...

 

R-tune is not an upgrade from S-tune, it uses completely different spring rates, bound/rebound settings, and antirollbar. S-tune is non-adjustable in any of these settings, but R-tune, to what I have heard, is user-adjustable.

 

What your saying doesn't seam to jive with nissan's marketing efforts, thier not painting the picture as you say it really is. If nissan is true to its marketing, the R-tune should be adjustable to the point of allowing the end user to adjust to a more aggressive setting over S-tune products. What is your information source for what you say?

 

From what I have heard and based off other R-tune suspension components, the R-tune is a fully adjustable coilover design, both height and firmness are adjustable. Below is a pic of the R-tune from the GTR-R34.... It seems to be a true track setup, and light years ahead of the s-tune.

 

Those are pretty...but if NISMO USA wants $1800 for the S Tune...I don't even want to think about what they'll want for those...any guesses? My guess is $2500-$2700...which is nutty.

 

I looked it up on the Japanese catalog that the dealer had which was, I think, published late 2002. I looked it up for the R34 GTR, and even though I cannot read Japanese, I could see from photos - similar to jran posted - the adjustments for ride height, bump/rebound, and camber. Also, in the text, I had compared the spring rate ranges they had (metric btw) and the R-tune's range was much higher. I do not recall the figures at this time as it was about 2 months ago.

It is somewhat disappointing that Nismo decided to bring only few select S- and R- tune components to the US, but I hope the number of items will increase in the coming years. I think Nismo is just testing the waters at this time.
