to be clear I was checking whether if what others were posting rubbish about your car which happens quite a bit, seems many like to bag out others, I had not seen you mention it at all. The main damage may have been done at another point in time and it finally gave up on the drive you did last and power is pretty much the only thing tat can break these stock shafts, but that power amount will vary according to how the car is driven, how grippy the tyres are, how hard the auto shifts etc
