With respect to the JJ Jump, after both the onboard and outboard vids, I cannot help think that the knuckle was damaged / cracked from before and the pressure of the hydraulic bump stop on the landing proved to be the final straw. There is nothing extraordinary in the approach speed or landing impact that would lead an 80 series tube to crack like that. Suspension behavior we can debate to death, but there are videos of other cars in this spot with harder landings, albeit none as dramatic. In the onboard video, it may be the camera mounting angle but the car seems lower on the right side when approaching the jump. In any case, to me it seems a case of going, going and gone rather than a clean karate chop.
