2012 M3W with about 57,000 miles. Stock compensator replaced at 19,000 miles. Centa unit doing fine. Total chassis replacement done about 3 years ago. Interim brace had been installed. The starting torque of the S&S is the main culprit there. One upper brace and two lowers had total failures. 3 aluminum sprockets, one SuperMax and now the stock steel sprocket which is a keeper. Cam belt at 23,000 miles. Fuel pump also went at around the same time. Sticking with ethanol free fuel from now on should help. On the 7th set of front tires and the fourth rear. I drive this thing hard at times but mostly just cruise.
