Thanks rpm,
I don't think the #12 team will fined either. But since I saw it written that there was rumors of some concern, figured it should be mentioned. My observation, from afar and without any real way to measure the impacts, was the rear end did come out from under the car after contact easier than I would thought. The commnetators mentioned also how the trailing arms were bending like "pretzels". Off the top of my head I can't visualize that happening in other tumbles I've seen, not that it hasn't happened before.
I gut feeling is that the NASCAR people just want to compare the damage to the black box data collected and see if further improvements need to be implemented. I think that the fact the car went airborne, somewhat attributable to loss of the right rear, might be lead them to investigate that area.
And without question the number one factor is that Newman was uninjured.
