Eibach Sportline 1.80/1.50 457/171-257

what do all those numbers mean?

sam

jon, did you cut'n'paste that line from my post? if so...
it means

front drop distance
rear drop distance
front spring stiffness
rear spring stiffness

i think... copy the first line of that table too in my post

thanks sam

so then how do you measure stiffness?

With a ruler.....

anybody have any intelligent answers?

i'm serious.... i want to know how to measure spring stiffness
and how the spring ratings are read......

sam

hehe.. aaron.. u're evil!!

jon... i think the first line in the table had something like lbs/inch for the spring rate... so maybe that means u need like 400 lbs to move the springs down an inch.. whereas the softer OE springs u only need like 200 lbs?

maybe... stab in the dark this is.

CBS autoracing glossary says its this...

spring rate: Amount of bounce a tires sidewall has when inflated to a certain level. One factor in deciding and determining how a car will be set up on any given weekend.

VARIABLE RATE SPRINGS : A type of spring that changes stiffness as it deflects. A variable rate spring uses coils of varying thickness or spacing to provide a soft ride when the vehicle is lightly loaded, but a firmer ride when the load increases. Only a few vehicles have variable rate springs as original equipment. On most vehicles, the rear coil springs can be easily replaced with variable rate springs to reduce bottoming and to increase the vehicle's load carrying capacity. Variable rate springs are also available for the front suspension

This will help you caculate as well
