So I will probably upgrade the Toyobaru to an Drexler clutch type LSD, too (as soon as I will get one, as sales starts here only in fall).

Viscous differentials react quite slow, you will more or less have already passed the corner before it starts to work. They are rev sensitive, not torque sensitive. I am not aware of anyone having a visocous LSD in a sports car, this type is a very good choice for SUVs.
Sports cars should be equipped with torque sensitive LSD. This is Torsen LSD or Clutch type LSD.

EDIT: Sorry, have overlooked you last post with the correction.

I messed up, I meant clutch type like cusco RS. Sorry. I fixed my post.
