Haven't seen this discussed here; seems like discussion has centered on the 1.5 Way (plus cooling)
Apparently OS Giken makes version called "DualCore" which is a Torsen combined with a clutch-type diff. With wheels on the ground, it acts like a Torsen; if a wheel lifts, it locks and becomes a clutch type:

It is listed as available for Z34 (if i'm reading this correctly)

Almost new reviews available in English
Thoughts on this?
It may simply come down to whether it locks hard enough on power, but in theory this seems good for cars that see track/street duty.
