i cant confirm but have also heard on 2 different occasions them ripping apart.
you really wouldn't think they would be able to with R&D these days, but who knows.

i had one in the car and had auto clutch rebuild it for 550
I am happy with it and these clutches don't really make the pedal effort any more than oem which is good for gt eastern hwy at 7am
