Another diff question

the OS giken, Cusco RS and MZ, Kaaz, and the Nismo GT LSD are all clutch type differentials, so by design they will not open up even if the inside wheel is off the ground. Clutch type LSD's though usually require setup and tuning for optimum performance for a specific usage (1.5 way or 2 way, what percent lock up, lock engagement ramp up Etc) and also use LSD specific fluids. A helical(or torsen) style LSD like the Quaife is a gear operated differential, and its bias characteristics and engagement isnt tunable but is very smooth and doesnt require special fluid to work correctly. but my design they have a weakness in the sense if the inside wheel doesnt have enough grip, it will open up. but its very user friendly and a "set it and forget it" kinda LSD, just doesnt have the performance potential as Clutch types
