In general you control sway with springs and balance under/oversteer with a sway bar. Contrary to what most beleive, more bar reduces grip. So adding a rear bar on a balanced steering vehicle will induce oversteer as the back now wants to slip and added to the front will cause understeer as the front plows into the corner. So if the rear bar is inducing oversteer, reduce the diameter of the rear bar or increase the front diameter and steering balance will return.
