Nevertheless, in a rear-drive car, any LSD from the factory is usually better than an open-diff.

A Torsen is a great choice for HPDEs and street driving. Clutch packs can be inconstant, noisy, and I've had them go on me before. Eaton TrueTrac was the preferred solution, and I loved the one that I got to try out. C5 and C6 road racers with any sort of serious investment in their cars all switch to Quaifes from the stock (clutch pack) LSD.
If you're driving your car hard enough on the street to feel the shortfalls of your Torsen, you're driving too hard for public roads or you've made such a hash of it that you've placed your self in a situation with one wheel on ice or hanging in the air. You're also going to be making a lot more power than stock. I highly doubt anyone is going to find the stocker lacking at stock or bolt-on power levels, especially for street driving.
