I jsut got mine, fitted to the car. How in the world are you supposed to tighten and loosen it though? I follow the instructions and put a piece of steel in the hole on the "nut" (my .5mm driver doesnt fint into the hole) and then i turn the rear wheel, and its frikkin hard to make it tight and loose. I think the carbon shaft has too much flex in it to work as its supposed to. It's easier just to take the wheel off and tighten as you would a normal f104 diff.
Also... the instructions dont say to put in the disc springs like on all the other diffs.... is the one o-ring on the "nut" all the spring you need for it? Or are people throwing in some disk springs as well?
