I can turn off ESD but apparently it will still come into play under certain extreme conditions. And defaults to full ON the next time you start the car.
I think it's best left ON for most drivers and most conditions. When you need it the most during a non-self-induced driving situation you will not be thinking about whether you left it on or not.
Anyway, I can usually modulate the gas just enough to give me a cheap thrill in fast turns with no big drama, just a little slide and wiggle.
I would agree disk-pack units are very useful for trucks with high torque and light loads, not for improving high speed cornering finesse.
There are after-market mechanical lock up units too, very expensive but virtually foolproof.
