I've run both the Quaife and the Cusco in mine. For a mostly street driven Z I would go with the Quaife. It will be very smooth and relatively maintenance free.
A clutch type LSD like the Cusco will be overly aggressive for a street driven car. I can't imagine DDng my Z with the Cusco in it.
Don't even bother with a VLSD like the one that came with the Sport or Nismo.
