If i was on a driving on a track. Would VDC save me from quite a few breaking loose incidents? And if you were really good could you drive with VDC on? or do you already?

i've never owned a X but driven my buddys..ok i'll take your word for it..haha.

VDC will cut power to the side without traction and drop your RPM's, thats a major no no, you want both sides firmly planted to accelerate out of turns, so no, you would want VDC off. I keep it on when it rains, when its not, i leave it off, i have too much fun smokin the tires.
