why would you call it a masterpiece? i agree that it really looks nicely! but as soon as it is installed this "feature" is gone. but what technical aspect would you emphasize to call it "masterpiece"?
did turner also try the gt4 unit or do they use it because they sell it?
i bought, dis- and assembled, installed and tested all lsd units available worldwide for the e92 m3 myself (except cusco, this one is still missing) and i even tried different setups of various units. so my ratings are based on experience and comparison. and my rating for the osg against the competition is... well... not so good.

but this is one of the most important things for a "normal" customer. how many customers of such a unit will disassemble and adjust a new-bought lsd unit prior to installation (except you and me *g*)?
the stock m3 e92 setup of the osg superlock is a joke. it doesn't lock at all. [and i can hardly believe that your setup locks effectively in the nsx when i look at the ramps, active clutchpacks and neg. preload setup you did... but ok, it is another car and another lsd unit.] the next setup i tried after talking to the osg guys was locking way to hard. after the second try i lost my patience and gave the next manufacturer a try as i am not the R&D guy of osg. i spent a lot of money for this "premium" lsd and i expect to also buy a setup that performs at least quite ok!

the osg website and the explanation of their own units is only proof, that they do not know themselves how clutch type lsd units do work.
