Personally I've best had success using the thin shaft types by YeahRacing. I think those may be quite a lot shorter, like 38mm but you need the smaller drive cups for these (rcmart.com)

From memory haven't broken any since (after sorting out my straight line driving with a servo saver) but I've stopped on road racing for a long time now (run on carpet and the "walls" may be of a wood compound or wood but with hard rubber outing).

I think the worst I've used are the JazRider ones which are even shorter, they're the thicker types.
