Also, I asked about the viscous coupler because it must disconnect like the haldex or synchro coupling because with 4 motion there is no center diff. Ever see how a dsm drives with a welded center?? Drag strip ONLY use is all I can say. Looking the haldex yields the same results. You wont be able to park or turn in any kind of a tight radius. it will bind and snap / break axles, drive shafts and mounts. Not something you want to drive if your planning on making any turns at all really.
It looks like that's the way it works and I'd assume they would want the front wheels to disconnect when traction is no issue.
Not trying to shoot down your "pipe dreams", just genuinly interested in the possiblities of the lambo parts and being realistic about potential downfalls / issues. Outside the box is the way to be
