Shell of these cars are the same as Cup Cars and they take a beating on curbs all the time. I get airborne at Road Atlanta at turn 3 and never saw that happen. Must have been a huge hit or defective weld at a seam

Could be the cup cars have the cage welded to the strut towers reinforcing that area or maybe the higher spring rates prevent bottoming out of the suspension.... Or both?

That is classic fatigue failure. Effectively microplasticity. I wonder if these cars have aftermarket rose joints? Could also be a metallurgical issue from a bad batch of aluminum...
