Not sure if this will work but here's a view from the back. Did a very wide angle to take a look at how much work I was doing on the wheel. Car wouldn't turn right, and when if finally did, the back end would come out. Retired after I lost third gear. I'm sure zinging it a few times going into the infield didn't help. I'm not above taking drving advice if anyone has something to offer. http://www.youtube.com/watch?v=sjBnDtcTBN4&feature=youtu.be
Your video was really hard to see, so I can't offer anything specific since I couldn't pick out enough detail. But Kyle's advice is good about a test day and/or coaching.
If your car is evil handling, its possible the set-up is not quite correct. I could see your hands working in turn 3. You gotta get the arc right to run through there at full power without much fuss from the ass end.
