spring source??

PostPost by: foggy » Sat Apr 08, 2006 1:39 pm

Haven't found a coilover spring, other than DB. Curious, who makes a
usable 105-125 lb/in 1-7/8 ID x 12" length coilover for elan fronts.

Thanks, all
Steve

Hello Steve,

hypercoils - http://www.hypercoils.com has a 125lb 1.875" ID with a
12" free length in their catalog, part #12D0125.


Has anyone in the list tried using 10" free length front coil
springs (with and adjustable perch of course) with any success?



regards


carl

10 inch free length front springs OK for 150 lb/in. Probably getting
to short for 100 lb/in springs and i would stic with 12 inch
freelength. 10 inch free length maybe OK for 125 lb/inch springs.

What works and does not depends on what ride height you want and what
amount of adjustment is available in your shocks.

Rohan,

Thank you for the advice. I just measured the spax shocks with the
upper and lower perches.
I think I can get the springs on and off without having to use a
spring compressor with the 10"
coils.

I am going to use your guidelines for spring rates on an S3 right
now, but for the life of me I
cannot find 115lbs rear springs in a 2.5" ID. Any suggestions?


Best Regards

Carl

I had mine custom made locally by a small local spring works in
Melbourne . I dont think the rate is really critical and plus or minus
10# will affect nothing. If you can get 110# or 120# sprngs that should
be fine as springs are not made to that close a tolerance anyhow.

A well respected suspension tuner I know told me once that most drivers
cannot feel a spring rate change of less than 50% ( even a lot of top
professional racing drivers he works with).

1 7/8" ID is a common size spring in the roundy-round world. They use
'em on midgets, mini-sprints, dwarf cars, and suchlike. Don't know if
you'll find any that soft and long, but there are many suppliers to
that community.

There was just a long thread on spring rates and spring sources on the
Europa group. You might download and search the knowledgebase at:

http://www.lotus-europa.com/knowledgebase.html

or just ask again on that group. There are several autocrossers active
there who can help you to the right F/R spring rates to suit your
purposes. The calculations seem to live in their heads!

I concluded that there are many sources of custom springs out there,
but that you want a reputable vendor to make yours due to the many
variables that can mess up a spring. The cost for a quality spring
would probably be comparable to or less than DB, who is just acting as
a middleman in this transaction.
