In one of your vids, I saw the gas light on. Are you doing this on purpose to save weight? Fuel starvation can def. lead to catastrophic failure when the engine is pushing as hard as you did on the vids, especially if you do it all the time. Do yourself a favor and take down those vids before someone who works for BMW decides to submit it....
