if you get a larger and stiffer rear bar, it induces more oversteer, and a front induces understeer. oversteer is when the rear will break loose first, understeer is when the front would break loose first. understeer feels like your car wants to push the front end through a turn, while oversteer is more like powersliding or drifting around a turn. i've got both bars in my accord, and they make it almost completely neutral, with a little hint of understeer.
