Actually, you will be surprise.
Springs rate determine how MUCH a car can move (ie body roll, squad, dive, etc)
Damper force determine how FAST a car can achieve these movement.
A common mistake most coilovers make is that they have too hard of a spring rate for road use, but will work great on track.
This is why alot of people complains that coilovers are "harsh" for road use, and why it is skipping all over the place on rough roads.
What ideally should be done is have a sensible springs rate for road use, along with a damper that have a wide range of adjustments.
That way, you can set up the suspension to be compliant for normal uneven road surfaces, then use the damping adjustment to slow/limit the body roll on a flat track surfaces.
This is a compromise but it is much better than having to deal with a harsh ride everyday only to have marginally better performance for the odd occasional track days.
Also, by having a damper with a wide range of adjustments, it mean you can use harder springs rate if you do decide to have a track only setup.
Your "range" of damping adjustments will be more limited as you cannot utilize the softer damping range, but it does mean you can have 2 very specific setup with 1 set of coilovers and 2 set of springs.
But most people would just like to drive to the track, turn the adjustment knob to hard and have fun... then turn the adjustment knob to soft and drive home. :drive:
