It's highly probable that BMW is covering way more than 1% of bolt snap issues (as they did with mine). If that is true then it isn't only driver launching issues causing bolt failure failure. The differential design was changed in the M5, M3 GTS/CRT, and will be the case for all future M cars, including the new M3/M4. That fact alone in and of itself is an admission of a design flaw and taken together with quite a few M3 owners' getting bolt snap/full differentials replaced under warranty would point to the same conclusion, i.e. design flaw.
