The fun will be finding out! I have a Group A bladed ARB to go on if needed, so could drop the front spring rate quite a bit if it would improve the overall grip.
What is surprising is that even on poor roads, running relativly stiff springs/ damping, the car feels compliant and planted, not crashy like some coilover set-ups? Gone is the horrid bouncyness of the old Konis as well, which may be down to age or poor spring choice, but a few cars I have driven with konis seem just a bit too soft?
Obviously it is all a compromise, with my Escos hopefully being as close to a Road/track balance as possible.
