with regards to using adjustable dampers,

the reason you want adjustable dampers is if you are going to change your balance (weight removal, weight addition, weight shifting (such as battery relocation) etc.

because during movement the front of your car will oscillate at a different rate than the rear of your car. Tuning this difference between front and rear oscillation is the nut of the problem.

Street cars are tuned for comfort so that even though the front wheels hit a bump before the rear wheels at regular speeds (40-80km/h), the whole chassis oscillates in unison.

When you modify your car by changing chassis weight and/or weight distribution and slap on after-market springs, you are modifying your balance. While "suspension kit" manufacturers (hopefully) do the background work for you, they tailor to some middle level feeling of "good." If this is not enough for you, then suggest looking into adjustable dampers.

If you are bad at math and prefer visual ques, you can and purchase some 3 way (2 way could also work) accelerometers and put one in your trunk, and one somewhere under your hood. then drive around and look at the outputs to see how damper tuning affects your car.

if you're hardcore enough (i've never done it) is to attach these accelerometers right on to your control arms at all 4 wheels and record data that way, but that's money and headache.
