You don't want to look at the springs rate, you want to look at the wheel frequency.
That is what the wheel actually see, and it is the result from calculation that include the springs rate, the motion ratio, and the corner weight (That is the basic).
If you look at the wheel frequency compared to the front, it isn't miles out.
I can't remember the exact number, but I recall it is around the 1.6Hz which put the suspension to what OEM Porsche would offer on their car.
It isn't high because it isn't meant to be high, it isn't suppose to be back breaking.
The ZetaCRD are designed to be a setup that you can daily and enjoy.
We don't want a setup that you will get annoy at driving on for hours on the freeway because it is not comfortable.
You can use the damper to stiffen up the suspension for track use.
But like you said, the spring rate is the base and you want to make sure it is correct for the purposes.
If one is after a more track focused car, then we will have a different setup.
