Hmmm... dont know about that. I'll pop the question again next time to them. All I've ever read about failing when launching is the clutch. At the same time, I've read about someone constantly launching his stock 33gtr and it took him 2yrs or so before he change it. Not saying I know how the condition of the car is but considering I have been treating her quite well + not much been mention about things breaking from people, I'd said 1 or 2 launches shouldnt kill it.
