Thing is, as power gets easier and easier to make, the stock diff gets more and more useless. It managed at stock power on tire tech from the 90s but better tires and more power really shows its inadequacy. I've heard good things about the helical diffs from an "oem feel" standpoint. They can do a better job of managing the power without being too clunky.
