A spring/damper system is exactly that... a system.
You take into account mass, position, velocity,
damping coefficients, etc. into the equation.  A
heavier mass (ie. westy instead of transporter)
requires more damping to keep the natural frequency in
check...

I've tried modelling a 4-wheel independent autombile
based on rudimentay spring damper systems, and it is a
beeyatch due to the indeterminate nature of the
equation, but the principles are the same, and
certainly not a "one solution only = stock settings"
kind of thing.  Consumer products are designed for the
masses - not you.  I personally like the ride of my
stock westy, but it wouldn't do for those wacky syncro
guys, for example.

Just like anything, it's a matter of knowing the
effects of the changes you want to make (stiffer
springs require stiffer dampers, etc.).

Have fun putting along,
