I was wondering, haven't seen this anywhere, does anyone have know the spring rates of the Nismo S-Tunes?? I have seen that the rears are progressive, so they should have two spring rates, but haven't seen any numbers on the fronts or the rears. I have to wonder if Nismo is hiding this info like they are doing with any info on their sways. Spending extra money on Nismo (over competitors) ain't cool especially when they won't even tell you what you are getting.

OK, I know this info ain't that easy to come by. I know that there are some vendors on this site that just have this kit laying around. There is a way to test these springs, could any vendors do us a favor and find out?? Don't make me start naming names............

Does anyone else have an idea??

All I know is that the springs are supposed to be 20% stiffer over stock. But it would be nice to know the actual rate.

Man, I haven't even seen the 20% figure, although as we have seen with many springs, this percentage could be way off. Main reason why I want the number is for comparison sake. Would be good to know where the Nismos fell in the aftermarket kits. Also, I believe I was mistaken in my first post in that the fronts are the springs that are progressive.

Them being progressive on one of those axles has to make you wonder why they did that. Were they trying to eliminate bounce?? Other kits also eliminate bounce without being progressive, so I just don't see that. I kinda see them as similar to the Tein basics right now, but I have no proof of it as noone has bought the basics and reported about them yet.

+30% front +20% rear

I didn't say that and I was neeeeever here.

little_rod--both front and rear springs are progressive. I don't know enough about suspension yet, so I won't even begin to guess why they went with a progressive set up instead of linear, although I'm willing to bet it was a good reason. lol

little_rod

LOL, if our "invisible" poster is correct, and I trust him as our stock spring numbers came from him also, then that could give us a little more light on the subject. Our stock springs, per Mr. Invisible are 347/419. 30%/20% increases would be 451/503 lbs/in. That is crazy close to 8/9 kgf/mm, which is usually what the Japanese go by. Now, since they are both progressive, they are both softer at first.

The Tein basics are listed at 504/504 lb/in. That is 9/9 kgf/mm. They are both linear, which is a good thing. Another good thing, they are much cheaper. Interesting, maybe worth a try, if we can find out anything about bounce.

how much are the Tein basics going for?

little_rod

tein's website has them for $890, but I think you can get some from some vendors somewhere for cheaper.

Tein are 671 lb/in, 671 lb/in = 12 kgf/mm, 12kgf/mm

little_rod

That is for the Tein flexs that you have. I am talking about the Tein basics.

Ah sorry little rod- my bad.
