Anyone have any idea what their spring rates are? Tried to find a website for them, but had no luck.

Alternatively, anyone know of a set of springs that are around 125 front/165 rear?

Marty:

Here is their website. It's really just a contact page (they say new site is coming soon) but there is a 800 number you can call for information.

sorry wrong thread

What are you talking about??

Sorry guys had two web pages open at once and by accident put that reply in there

In case anyone else is interested, I just talked to the tech rep at Suspension Techniques. He quote the following spring rates:

Front: 125

Rear: 182

Drops the car 1".

What application are you using these for Marty? Autocross or Daily Driver? Will they give a harsh ride?

Hi James,

I am looking for springs for my dual purpose car. It is a 71 that I drive on the street and do about 6 high speed track events per year. So, I am trying to figure out the optimum balancing act.

From the research that I have done so far, it seems that 125 front / 165 rear would give me that balance. It will be stiff enough to give good performance on the track, without being punishing on the street. Unfortunately, I have not found anyone that makes this combination. I need to do some additional checking though. I beleive Eibach's website says you can get springs in any rates you want. We'll see if that is true.

To help you understand the whole picture, the car has Koni shocks, 1" front and 7/8" rear sway bars. This winter I will be installing PU bushings. That is what got me thinking about the springs, since I will have it all apart anyway.

Actually, I am not really unhappy with the way it handles now. It handles pretty neutral and reasonably flat in the corners. It just seems I should replace the old stock springs while I am in there.

do these rates apply for the 280z springs also?

Thanks Marty.

I'm about to pull the suspension off mine and just gathering a few ideas about what I will do with my suspension. I'm thinking Eiback Progressive Springs as they might give me what I'm after, but its always interesting to get another opinion.

Once you finalise the springs could you update this thread?

Still at MOT?

Z boi, These are rates specific to a 240Z.

James, How do you use your car? Progressive springs may be ok for a street only car. Quite a while ago one of our experienced racers said to stay away from progressive springs on a track car. He said it is down right scary when the springs make an abrupt transition in spring rates.

Yep, been at MOT for 14 years now. We're having a pretty good year.

I'll keep you posted on what I decide. It will be a few months before I can free up some cash, so I'll be going through the tear down mode first. Take it apart, clean and POR -15 all the parts. I already have the PU bushings. Springs will go on last. Its entering winter time here, so I'll have till the end of March to finish it up.
