Can someone please shed some light on ceramic diff balls and thrusts? I'm about to build two XXX-CR diffs with ceramic throughout, but I read somewhere else that the ceramics were so hard that diffs slipped too easily.
Im definatly ordering a complete set up for my xxx-cr and my sons mf1 xxx-t. Any idea where to get metal diff gears? im putting alot of power into the diff with a mm7700 and worried im about to rip the plastic gears apart.

Yeah he sandbags! I hear there's some really fast racing down there at McColloughs lately. What days do you race?
I overlooked this thread all day, sorry. Practice is Thursdays and we race on Saturdays. Racing starts at 3pm. Visit the website and forum for more info. Give Mike a whack from his old buddy Dave

So how much performance increase do you get, and what does it do? The only thing I can think of is the wheels would go more traction because of the smooth powerband or something.

sort of... but a new factory diff should feel perfectly smooth when new and can be maintained to last.... but some manufacturers stock rings are just horrible.. especially their thrust bearings... but I'm going to name whos. BFast diff rings last longer and need a little less maintenance because they're actually flat, compared to the stamped out versions that are produced by some of the manufacturers that tend to be almost warped it seems. Check out the website, there's actually a pretty good comparison that will show the quality difference. If your diff's not smooth, your car is not going to corner well... that's the simplest way to put it.

Another downside from not having a flat diff is that proper adjustment can be near impossible to achive. The diff will have a "hit and skip", tight in one spot and loose in another action. This will cause the "hit" areas of the rings will wear very fast, the diff becomes loose. So you snug up the diff and the "hit spots wear again quickly. By the time the wear groove is even around the ring you diff is full of debris. The balls are now damaged from running over the compressed debris and are now chewing the rings up creating more debris and so on. If steel balls are used this process will happen at a much faster pace. A smooth diff will break in quickly and stay set longer and require less disassembly for cleaning and re-lube.
