I had gear diffs in my DB01R, and they leaked out in one race night - made a mess of the cases and belts. Pulled them out, rebuilt them using some green slime, and same thing. They leaked out around the outdrive, not at the case halves, so the gasket was not the issue, it was the o-ring and the three spacers which were not doing their job. I wanted to run gear diffs so badly as well. I have not tried a thicker/wider spacer yet, that might solve the issue - but a well built ball diff still seems to be the way to go.
