Looking at your youtube videos, imo, it looks like the car is porpoising ie., rocking front to back after the initial hit, unloading the slicks. - You can hear the engine loading differently as it bounces around.
Brent...My bad! My memory needs a darn tune-up! I could have sworn I had the Rancho's set at #9!....they were actually set @ #5...maybe too soft,and reason for the porpusing! #5 is my street setting,by the way.
