What I really like is when there's loose traction (dirty road, wet road, etc.) I don't get the wheel spin with the stock diff in which the overly aggressive computer detuning the car for a few seconds.
It does boggle my mind that a modern sports car would ship with an open diff... I mean if a much, much, much cheaper S2000 had it...
