The spring rate is only half the story. If you liked the balance with the old springs, you will hate the new...will push quite a bit IF the sway bars were not changed to compensate for the change in roll stiffness. What you need to know is the actual wheel rates of both the old and new setups (the combination of actual spring rate plus sway bar rate) and tune accordingly.
Since you were happy with the balance before, I suspect you will want springs very close to those and just increase roll stiffness with bars. Chuck
