I have experience breaking gears on 4x4 trucks. From all of the failures I have seen on the S2000s I would say that the problem is in the case and pinion support. Under power the pinion deflects causing the contact pattern against the ring gear to change and BOOM. This could happen slowly over time weakening the gears or as soon as you drop the clutch. I think that it would be possible to build some type of ultra strong diff case/cover to prevent these failures. http://www.currieenterprises.com might be able to do it. They make a lot of cool custom stuff.

Sorry that I missed the beginning of this thread...I destroyed my differential and spoke plenty with Comptech about my differential and theirs. If you look at this picture I can point out where the failure was on my car.
You should note that this is a differential with the Comptech bearing caps (in shy silver with the golden bolts going through it). My differential actually snapped down where the ends/tips of the bolts are inside the U-shaped part of the assembly (someone help me with the part names). The bearing caps were snapped in half, and the differential busted through the housing. Whether it was the bearing cap or the U-shaped piece that snapped first is not certain. My plans for building stronger are to strengthen all possible pieces. The differential was upgraded to Kaaz, the Comptech billet bearing caps were installed (I think they come with different, longer, bolts) and next is to strengthen the differential housing with cryogenic freezing. Some of these are to prevent destruction while others are to limit the damage in the case of a failure. Comptech had their differential blow (the car was in the hands of a magazine writer) and their housing was intact...so they didn't have to spend another $600 for the two housing pieces.
I won't be doing the cryogenic freezing until I get my racing axles made. I'm purchasing a set of used axles now that I will use to send off to Drive Shaft Shop to use as a template for the racing axles. This won't happen until end of the year as most of my money is already going towards other things (boost upgrade).
