By the law of Hooke (not related to Cptn Cook) a sring has a constant rate derfined in force per length:

lbs per inch.

well most sprigs. fancy springs may have a progressive rate.

if you load your springs (i.e.springs with a value of 500 lbs per inch) with 500 lbs it will lower one inch, 1000 lbs equals 2 iches.

if your spring is mounted preloaded, as is often in coil overs, your car will not lower before the amount of preload is exceeded.

A common automotive spring, although, may have due to manufacturing, another rate for the first 1/2 inch or so. that is why cutting is a try and error thing, plus the ride is harsher for small bumps as mentioned earlier.

call KONI or Rockwell springs for more information.also you may read the chapter on springs from Carroll Smith's "Engineer to win".

What was the outcome of cutting?
