I have tried it in mod, but I have to say overall I'm quite disappointed. I already changed gears two times, because they were stripped.
At first I used 900cst oil and now I use 3000cst oil. No difference in handling!
So the gear diff itself runs very good, very consistent and great handling. But after a few runs the gears feel terrible. They grind up to each other and it is very hard to spin the diff. Almost feels like a spool. Freshly build no problems, but after a few runs it is done with the smoothness.
That's why I changed to 3000cst, in this way the pressure on the gears will be reduced a little bit.
I opened the diff a few times and saw the shims were bend like earlier been mentioned. So I replaced them, but still no good. So carefully inspected the gears, but they all look fine (this is later on in the process, because I already stripped 2 sets of gears).
So I don't know what to do right now. I have thought about other options, like changing the shims for thicker ones, but every solution has its down side.
The only thing I can come up with is to mod the inside of the housing like P.I.M.P. stated, in order to put a larger and thicker shim in it. But that will be some serious modification.
I have also tried a double gasket as well, different kind of sanding techniques (even no sanding of the gears), but all that doesn't seem to help much.
So averall my conclusion is, that it isn't really suitable for modified. Bummer.
