TEIN Super Street - comments?

[Coxy_]

Hey All! Ive just ordered a Tein Super Street kit for my 34 (if theyre no good its too late now anyways!! hehe) - has anyone used these before? I heard theyre ok for our roads cause they can be adjusted to be quite soft but also give a good feel on the hard setting?

also with adjustables is it a given that the lower you go with them the harder they should be set?

[Aya]

I also want to buy that super street as well for my R32 GTR. it says on the GTR magazine that they tested on a R33 GTR and pretty good. Also the price is the cheapest one that can use the EDFC system in Tein suspension kits. Let me know when u got it.

[Coxy_]

no worries. I should have them in about 1 1/2 weeks (im counting to the last minute!!! hehe) - Ill post up as soon as Ive given them a good test

[Reedy]

I got some for my r33 gtst last week and I havn't found the ride to hard at all, you definetely feel the bump more and have to slow down on bad road but not uncomfortable. The handling improvement from the standard gtst is like a different car and adjusting shocks makes a large difference for body role. As you lower the car you actually losen the springs, so they are actually softer for lower and harder when the car is higher.

They feel great to me, though I haven't had much to compare against. I have never used adjustable suspension before, but I found that it can make a huge difference on the track. Was understeering terribly on the track, a few turns of the damper and the understeer was almost gone.

The ride is actually better (not as hard) as my old stuffed shocks and lowered springs. So was a huge improvement everywhere in my R33.

cool! thanks for the info guys - what setting do you guys usually leave the damper on for road driving? is it still really hard on the hardest setting?

[Sydneykid]

What's the spring rates?

[Coxy_]

??? Ive looked for it but I cant find it anywhere??

All I could find was the spring info 200kgf/mm2 I think it was??

[Reedy]

I had my damper on 8 and porbably to hard for road going to soften it a bit but still only trying the settings out. I read 4.0 kgf/mm in the manual but it is in Japenese.

Sydneykid: Pretty much all the information is available here:

http://www.tein.co.jp/ssdamp2ne.html

And just because I am nice, I worked out all the conversions (there may be an easier way!!). According to the booklet I received with the suspension they are 4kgf/mm front and rear.

From the references:

1kgf/mm = 9.80665N/mm

Therefore:

4kgf/mm = 39.22660N/mm

From the references:

1N/mm = 5.714 lbf/in

Therefore:

39.22660N/mm = 224.1407lbf/in

Therefore the answer is 224lb springs front and rear.

PS: Thanks for all the excellent posts Sydneykid, when I see your posts I stop and read them from start to finish.

[Sydneykid]

I do it this way.....4kg/mm X 25.4 (mm's in an inch) X 2.2 (lbs in a kg) = 224 lbs per inch.

Which is OK for the front, but still too high for the rear. I would guess that they are still trying to compensate for the low rear anti roll by running a higher than necessary (to hold the car up) rear spring rate. A stabiliser bar upgrade is a technically superior solution. In the real world that means it won't compromise the ride comfort as much and allow much better (less wheelspin, more traction) launches.

[halz]

Well your way made a lot more sense! Glad I still came up the correct answer though

I really like this suspension, its hard but not too hard even for my 100km/h country roads. Compared to with my previous stuffed stocks with lowered springs its pure bliss, I don't have much else to compare too I'm afraid.

I had the front and rear set at 2 points (12 point adjustable from memory) from the softest setting. The rear was also set way too low (probably 30cm centre to guard). I found that in a straight line under acceleration you could feel the rear compress significantly and it was very difficult to get any wheel spin at all (i have allow subframe bushes too) - probably pretty good for the drags but not so great round the corners.

I've since changed the rear to about the 5th or 6th point (in the middle - probably too hard this time!) and the the front to the 4th setting. I've also adjusted the height according to the spec sheet ~ 33.5-34cm centre to guard front & rearl. Very much looking forward to testing this out at the next track day... once I've replaced the turbo

I'm looking at getting some upgraded front and rear sway/stabiliser bars from whiteline - would this be the next logical progression or would I be better off to get some more caster in the front?

[Coxy_]

Thanks for the info guys! it sounds like I made the right choice

You guys wouldnt happen to know what the optimal ride height should be set to if there is one?? I want to get it low (for looks) but I dont want to put the car off balance doing it

[halz]

From memory the spec sheet said 33.5cm centre wheel to guard. From the posts I've read (mostly Sydneykids!), the reccommendation is 34 - 35cm.

Hope that helps

[Sydneykid]

so they are actually softer for lower and harder when the car is higher.

Sorry Reedy, but I need to kill this quickly............

A 200 lbs per inch linear rate spring takes 200 lbs to move it one inch, or if you prefer....

A 3.5kg/mm spring takes 3.5 kgs to move it one mm.

It doesn't matter whether that is the first inch (mm) or the 10th inch (mm) it still takes 200 lbs (3.5kgs) to move it one inch (one mm).

The amount of preload is determined by the weight of the car. If that corner of the car weighs 400 lbs (182 kgs) then the spring will need to compress 2 inches (51mm) to hold it up. But it still takes 200 lbs (3.5kgs) to move it the next inch (25.4mm).

Progressive spring rates USUALLY compress all of the softer rate just in holding the car up. ie; they are progressive to make sure the spring doesn't go loose at full droop. They are not progessive to make the ride softer initially. This is not ALL progressive sapring just Most of them.

Hope that makes sense

[Reedy]

So what your saying is when I raise the car and tighten the springs in the coilover the springs aren't any harder as they are progressive?

[Coxy_]

I just received one of them!!!! (yay!) - gotta wait for the rest now..

Did any of you guys sets come pre-set with what at least Tein would say is the best settings for the car?? I was reading something on the internet and it sounded like it says they are already pre-set?

[halz]

There is a sheet in the box with the recommended settings - also see the above comments. You should experiment with the stiffness etc. to suit the way you like it

[Coxy_]

cool - ill have a play around with them when i put them on and let you guys know how i get along... thanks for all of the info guys youve been a great help!!!
