Personally I think 450/500 is too much spring for a car with an open diff and often results in wheel spin on corner exit. Also way too stiff for street use with PSS9s. A more sophisticated dampener may be able to manage stiffer springs.

The voodoo is getting your tires, running weight, spring rates, dampeners, sway bars and driving style all working together to control your contact patch instead of fighting each other. Getting it exactly right is harder than it seems.
