1. My transmission was -and still partially is- based on 996 turbos's, so no LSD there to start from
2. 997 Cup = Motorsport part. The other option would have been a 996 Cup one. I did not consider a street car part.
3. It was then conveniently available...

996 Cup: 40 / 60 locking value
997 Cup: The locking torque of the differential is 40 % (power) and 60 %
(braking) (Dynamic locking value).
