mancini tube upper control arm failure....

Maybe it broke after the curb and pole impacts. No proof otherwise. Curbs and poles are not something you drive over in spirited or racetrack driving.

Ok, it shouldn't break the weld like that. But it shouldn't hit a pole or jump a curb and speed like that either.

i agree with that. but that arm is not bent enough for that weld to break. for that arm to break it should be mangled. even then the weld shouldn't have broke. we will probably never know which came first the crash or the broken weld. the one thing we do know is the weld broke and shouldn't have.
