Installation of a ball-jointed Toe Control Arm (like the Rogue Engineering part) removes two rubber bushings, resulting in a further softening of the suspension."
Good info on the trailing arm crash safety design.

Basically since there is no bushing wind up (which contributes to spring rate) with a ball joint, you are decreasing the spring rate, thus softening the suspension.
