2013 Nascar Cup Chassis Changes

that downtube has so much bend in it I would think it would fold like paper in a roll-over situation, especially at the speeds they tend to roll them at. It doesn't surprise me at all they saw a lot of chassis flex due to that. Note where the triangulation is added, it is all to support that wicked bend, and then the downtube from the top center also adds similar rigidity by bracing the center of the halo. I remember the first time I saw how bent those tubes were in the cars from inside camera shots - what a horrible idea.
