Input Appreciated: KW Street Comfort vs. Club Sport

I remember reading somewhere on here that the Steet Comforts are superior in design to any of the KWs and are actually similar to the Club Sports. Is this true? If so what is the primary difference? Suspension is definately my next mod and I'm interested to learn about the differences in design. Thanks!

Pretty sure the major difference between Street Comfort and "V serie" is the springs. "V serie" use progressive springs while Street Comfort and Clubsport use linear springs.

I don't understand how the Street Comforts supposedly have a higher spring rate but are softer..
From the sticky:

KW v1-v3 (non M3)
Front: 190-256 lb/in (progressive average)
Rear: 545-570 lb/in (progressive average)

KW Street Comfort
Front: 285 lb/in
Rear: 625 lb/in

KW Clubsport (non M3)
Front: 400 lb/in
Rear: 570 lb/in

I believe there is a difference in the damper design. That's what I'm trying to get to the bottom of. I'm looking for a robust suspension.

the spring rate is higher but the compression dampening is software....
