Failure to 904 drum “possible” but I’m betting the rpms required to achieve this phenomenon are up there with the aftermarket 727 parts due to its smaller size basically putting it above a threshold that we’d seldom see. In my conversations with a couple of shops that have been in the game awhile neither have encountered this happening to a 904.
