pimp: that is how the ofna torsen diffs are designed, they have an exploded pic in a manual on their website (im pretty sure it's what your talking about)

brushless boy: the fioroni diff is a kind of torsen diff just not the worm gear type that ofna call torsen, and theyre nothing like the diffs in the new xray xb808 at least (well, according to the exploded view in the manual which shows a standard oil diff, i dont own one to pull apart here though)
