The issue with the stock crowns is the wearing of the channel for the motor shaft, right? (too tight? too binding?) Or is there some issue with the mesh itself? If it is the wearing/friction, then cutting off the end of the motor shaft and adjusting everything tightly, without too much side axle play, would seem the simplest solution. Assuming that would be legal….. I have not had a chance to run my car at all, but that is probably the first thing I would try.
