Launching front tire camber? And shock travel.
Have you checked "toe" at different ride heights? From the video, it looks as though the front tires are toe in pretty bad...hard to see but I sure would check toe at 1" increments from ride height to wheels up. This may be your problem... Toe should not vary more that 3/8" or less would be ideal! This is my car, I have worked hard to achieve very little bump steer on wheels up situations like this. [less that .060] from ride height to wheels up.
