better not tell Porsche. new 911 (i believe) allegedly does have LSD capability but only via the ABD sort of control, no conventional internal clutching
i don't understand your friend's 540 situation but i seem to recall, years back, having my non-LSD 944 idling in-gear on jackstands and only one rear wheel was rotating and i was able to grab that rotating wheel and stop it and that made the other wheel begin rotating, seemingly very much redirecting the torque to the other wheel just as grabbing a spinning wheel via braking (ABS) would. i'm trying to recall in my head the inner working of a conventional LSD but it's a bit foggy. but it seems to me, based on my little 944 experiment and vaguely on what i can recall on the internals of a differential planetary gearing setup (LSD or non-LSD) that stopping the spinning wheel from slipping would indeed redirect the torque to the other wheel which is the whole concept behind this new flavor of LSD technology. then again i'm no expert here just the naturally curious sort - and i hate thinking about conventional LSD's wearing out and the expense of replacing them, would much rather think of only rear brake pads giving up their life.
