The corner weight numbers look better now. Thanks for updating it.

and, they suggest that, based on experience, ride frequencies for non-aero sedan race cars should be in the range of 1.6 to 2.0 Hz with the front higher (p 605). "Front higher" is in direct contradiction to what is required to reduce pitching oscillations in lightly damped street cars.

It seems like they may be neglecting the use of a front sway bar. If using soft front springs together with a moderate front sway bar, then its possible to have high roll stiffness and ideally tuned pitch characteristics at the same time. That assumes we care about road car ride quality and chose the damping ratio for that purpose. In that sense, you seem to be clear about your objective which is totally reasonable.
Thanks for the great thread so far. The detailed info and your explanation has been very useful. I've swapped springs and sway bars a couple of times already and I'm still learning.
