CPS for mini

[Shannen Durphey]

I've had a flexplate come apart at about 4K rpm.  It separated the
auto trans from the engine, broke the starter, and sent a piece of
starter ring gear through the floor and up through the heater box to
wedge in the heater core.  It takes more than pretty stainless to
prevent that kind of destruction.
