I've broken mine twice now...second one broke about a week ago. Curious (and rather angry) I looked for the possible culprit for this. It appears that the diff spring gets bent with use and therefore applies uneven pressure to the plates and unwanted vibration to the screw = it snaps.

Gonna try a new spring from another company and see what happends.

I broke 7 diff screws in my first cyclone and zero in my 2nd. For minimal breakage use the Delrin outdrives the associated diff screws and nuts, and put a small washer in the outdirve before you put in the nut and you should have decent life out of them. There is a link somewhere where Hara shows the best way to build the diff. I also used all ceramics in my diffs and they were butter for 3 months till I sold my car.

For those who are having problems with snapping diff screws, I haven't broken anyone so far. I'm using the titanium one from HB, but the one from Edit will also work. Another thing I always do is loosening the diff screw at the end of a race/practise day, so there isn't a constant pressure on the screw (only when you use it).
