I picked up a set of Saleen Coilovers a few weeks ago on the cheap, the catch was that they came without springs.
I’ve been talking to someone that has access to custom springs and can get me any rate that I want but he’s not sure what would work for my car.

The car will only be driven on the street and mostly on the highway, I also plan on lowering it a fair amount once the coils are on.

So far this is what I’ve come up with, for the Fronts 350LB/in and for the rear 200LB/in. I’m open to suggestions in regards to the spring rates.


Thanks in advance,

 

If your biggest concern is ride quality you would be best to go with a progressive rate spring. Linear springs are better for handling but can get rough on bad roads. You can google spring rates to see what the manufactuers use. Springs are also pretty easy to find in the for sale sections.

 

You may want to contact a mfg like Hypercoil.

http://www.hypercoils.com/

Have used their products in the past with great success.

 

You could check out the Steeda equivalents:

Looks like they use 200-250 front, and the rear 162 or 175.

 

Strano lists a few others:

H&R ClubSport
http://www.stranoparts.com/partdetai...=135&ModelID=5
Includes 630 lb/in front springs, and 515 lb/in rear springs

Those are basically track-only, though.

 

I can supply the entire Hypercoil line, and help you with spring rates too.

I can tell you that I think the H&R's are way too stiff. 350/200 isn't a good combo, but what I'd use would depend on how low you want to go... the lower the more rate you'll need.

Happy to help, give me a buzz. 2.5" coil-over springs run $65-80 each depending on size (there are cheaper ones, but they are pretty much junk). One thing to keep in mind is that the dampers you have aren't super high-end and as such we also have to keep the spring rates more moderate.

 

Thanks for the suggestion but I was trying to get more into specific info.


I'm going to be using those, thanks.

I’m not to sure how well the Steeda springs will work but I’m thinking they might be too soft with the drop I’m going with and those other springs seem a bit to stiff for street use.


I’m getting the springs at no charge otherwise I would contact you for advice, don’t really want to waste your time.
I see a set of BMR adjustable front CA in the future, I really like the idea of them being able to be adjusted but not to sure about their durability, my other choice is to go with the Ford Racing front lower CA and I see that you sell those.

I think at this point I have a good idea of what spring rates to go with for these coilovers. From what I’ve read these past few days I think that a 350lb/in springs for the front would be a good choice matched with a 310lb/in springs for the back. I’m hoping that these rates are good for the streets and occasionally also at an empty airfield, going to be doing some top end runs with my car. I plan on lowering the front about 1.2” and the back to 1.7”
I’m mainly looking for some good stability with a half way decent ride quality.
