If you can corner weight your car, I can get critical damping and wheel rates for certain HZ range, which might help you a bit, my latest calculator version should be quite close to perfection already. But it still might be challenge to hunt shocks that are in correct range, however it would at least give something to hunt for.
Something like 1.9Hz front and 1.3-1.5Hz rear might be quite good goal, but to get it perfect it would be perhaps good to prepare for getting several set of springs as in practice testing different combos will be only way to really get into what works for driver. Rear is simple in there that is is adding leaf to get it stiffer. Shock adjustment is mostly needed if different springs are used, but as it is darn hard to get perfect shocks often adjustments will help to choose compromise that is least worse, which of course don't need to be bad at all, just not quite perfect either.
In theory it should be then possible to achieve a vehicle that is better than most, but all this is just hobbyist theories which might be greatly flawed, let that be disclaimer, I don't know yet everything and lack of opportunities to test all in practice is certainly not helping, but stuff should be rather solid and it should result quite bit better than approach without numbers, there just is no guarantee which is good to mention so that you know how much to weight on theories
Tune to Win should contain lot of same stuff and it is very solid stuff in there, but still it would need to be finetuned, In F1 McLaren, Ferrari and Minardi certainly had same knowledge of these basic things, but their fine tuning made quite bit of differences, however with Minardi's level one would be king in many other motorsport class
It is rather interesting stuff.
