This can SO get out of hand.....

(I think) Torsens are never locked.  Locked means 50/50 split, no matter
what.  Both axles (or wheels) turn always in sync.  With A Torsen this only
occurs when driving straight and level, and it's still not "locked,"  Does
that make sense?

There must be some good web site on this.  But I'm going outside and drive
the Z06 to a cookout.  It's far too nice outside (80+ degrees in upstate NY
in APRIL??) to think about Torsens.

And be aware... all of the old time listers will remember the Torsen
"thread" from hell.... which eventually got banned.  =)
