Thankx for your input. What Video number you saw this? There is some time and changing between the movies. The last stand is number 7#. The #6 was with long travel set, but there is no way to use this useful.
I do not know, how heavy the car is in #7. (more than 15 lbs (7kg+))
But the body hit the wheels not the floor (; If I could set the body higher the soft problem increases. (lever rule)
