Hi Sparoz ! I'm not enough of an expert to answer your question technically. But about KW's, the main difference between V3 and CS is firmness. To the extent that a CS is only advisable for regular trackday fans. I'm running KW's DDC, which is basically an electronicaly adjustable version of the V3. Using a switch installed on your dashboard, you can adjust firmness between Comfort, Sport and Sport+. The latter is for track only !!
Or using an app on your i-phone/i-Pad/i-pod, you can create a wifi network, and adjust your damper's firmness by the percent. And it works perfectly !!
Mechanically, DDC dampers are adjusted by altering the valves inside the damper itself.
If you're a total trackday nut, go for KW's CS. But for most of us, the DDC is The choice.
