Take the springs out of the shocks, usually marked on the flat edge that faces the mounting plate.

You can measure the spring rate via the wire diameter, the number of coils and the spring's diameter.
Drop me a mail if you want a spreadsheat with the formula. Addy below..

130 090 are standard avo numbers, I think they dictate the open and closed lengths (ignoring bump stop). Check their website for clues.

If measuring and calculating are not to your tastes, then you could measure the length, put a heavy weight on the top and then measure the length
again (weighing scales in a big vice could work too). The weight divided by the length-change is the relevant rate. Not sure how easy this is to
do, but its cheap and will get you started.

A rate calculator applet

Note that not all spring wire is identical though.
