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.
there still smooooth

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).

It changes your roll center. You're probably best reading the following link: http://home.scarlet.be/~be067749/58/ , go to suspension>roll center.
Another thing you can change with it is the anti-dive/kick-up (front) and anti-squat (rear).

I have been running the Cyclone for almost a year now and I have broken maybe 3 screws (2 in 1 day really pissed me off!). But... on the whole, I don't really see a problem with the diffs the way that they are as long as you know how to build them in the first place, and know how much tension to give them. The main problem is that people tighten them up too much. You need to give them a little bit of slip otherwise it will snap.
Also... its very important to break them in, particularly by hand. Andy showed me step-by-step how he builds his diffs and by simply breaking the diff in by hand, you really shouldn't have a problem (I haven't broken one in around 3 months, and I haven't had them loosening off too). The main thing is that the diff feels really free, yet also has a very strong action. When you build your diff, build it loose and tighten it up in the car. That'll help prevent you to not overtighten.
