Is that asking for too much from a single adjustable damper? Or, do you think you've already achieved this result with your current product?

That is what we have done with the ZetaCRD within reason.
Springs rate isn't out of this world.
Softer damper setting will have low cracking pressure as well as reasonable damping force leading to a compliant ride especially over uneven road surfaces
Stiffer damper setting will have increase cracking pressure as well as higher damping force leading to better steering and damping response.
That is one of the reason why adjustable compression and rebound combined damper is essential for providing a good fast road & track suspension.

To be honest, springs rate is but one of the item in calculating vehicle dynamics.
Roll centre, corner weight, anti roll bar, tyre compound, etc all play a role.
The springs wheel frequency is a good base because you know if you are using a road car, you want to keep those wheel frequency under 2.0Hz
And it is a level playing ground for any car, rather it is a FR-S or a Porsche, the car may change but the numbers stay the same.
Where if you have a race car then you can go over it.
For most clubman driver, we find around the 2.5Hz is where they end up having a happy medium between body roll control and predictability.
For professional race car, we have gone into mid 3Hz, and sometime even info the low 4Hz depending on what we are doing.
