While I can understand the enjoyment of a "dancing" rear end (on a Porsche and a beautiful woman), I am in the camp of stablizing it more.  I have driven and raced dozens of 911 variants over the years, and the danciing rear end has always been difficult at best to control consistently, and at worst downright dangerous.  Spin outs can happen so suddenly, and few mortals can control them effectivelly.  If you do enjoy this oversteer tendency, please, please, please be careful....
