steering and suspension Currently Offered Aftermarket Springs - Spring Rates?

[danco_]

Hi Gents,

 

I vaguely remember seeing a thread regarding most current aftermarket spring offerings. There was also a thread that compiled measured spring rates for these springs, both front and rears.

 

I am mostly after linear spring rates at this time, as I am looking for a suitable rear spring to compliment the front coilover spring (7" @ 300lbs/inch of compression).

 

I'm looking for a rear spring in the 240lb range that will compliment the front 300lb springs. Any suggestions?

 

Does anyone have the specs on IE's offerings? Both Stage 1 front and rears, Stage 2 front and rears, Korman springs, or any other company that offers springs for the 2002? 

 

 

 

 

Thanks! I really look forward to hearing your responses. Or you know, if someone can link me to the thread was already made. 

 

 

 

Yes, I searched. 

 

 

Regards,

RD

Call Jeremy at Ireland.  He'll sell you some springs that will work- they know how to 

do it about right.

 

You can also 'make your own'  (really, what Ireland does) by cutting down some 5"

stock car springs.  It's not hard to do.  You DO end up having to experiment a bit

to get the rate and ride height to work just right.

 

Whut I done and gone done...

I'll give Jeremy @ IE a call today and see what I can get out of him.

 

 

I was hoping someone has details of spring rates for both F & R springs for IE's Stage 1 and Stage 2 springs. 

 

I'm thinking that if the Stage 1 front springs are somewhere around 240lbs, I can easily use those in the rear. Or even if they are around 200ish lbs, they will likely need to be cut a bit to match the front stance, and the spring rate should stiffen up with every cut. 

 

I wish I had details.

iirc stg 2 by IE are about 270 ish.......

i would think w/ 300 lb frts, that the ie stg 2 rears are about perfect to start.

Yeah, Jeremy will be able to talk rates with you, certainly!

Remember that because of the location of the spring on the rear of an 02, quite a way forward of the axle centerline, the real spring rate at the center of the hub will be much less that the rating of the spring.  I know that on an E30, the spring rate at the wheel center is about 45% of the rate of the spring itself.

Ireland will actually give you the rates. their springs are custom and they know what they are getting. The reason you do no see rates from other manufacturers that sell you "Lowering Springs" is that you never know what you are going to get. The variance on those is so huge that they will not publish the rates.
