Also, do you have vendor data on the stiffness of the new springs, and how that compares to the stiffness of the stock springs?
I have driven the car with and without the Hartge springs. Not on a track, but when using EDC the ride hardness does change in the same manner. And the car behaves in the same way with the advantage of a lower centre of gravity. If you need more technical details I suggest you email hartgeverkauf2@hartge.de and write to Jorg.
