Well in the commercial, as I recall, the rear tires are not spinning much faster than the fronts. So the concussion of landing wouldn't shock the drivetrain anymore than my turn 7 Road Atlanta qualifying experiment where I left my foot down, left foot broke, turned off the key then turned it back on as I exited. Was a suggestion from a friend who was on Paul Newmans team. Well I'm here to tell you that was the single largest shock that drivetrain ever got. If it was going to break, it should have done it then but that is one reason I bought another diff for it anyway.
