You have to consider it as a whole. Do you have stiffer suspension? Heavy sway-bars?
Personally, I don't like sport bushings or stiffer bushing in moving parts(Spherical bushings are a different category). What will happen is that with a harder rubber, the bushing will induce a larger amount of spring rate to the system. Currently with the bushings on the car, the suspension is able to move around during its travel adding a minimal amount of spring rate. If you replace with something stiffer, the overall effect would be similar to replacing the springs on the rear. How much more tail happy it will be? I can't tell you. You can measure how much force it takes to move it through its range before and after.
