Options for LSD for 986 S, what all is available?

[RyanPerrella]

So i am doing some research and am curious what options there are for an LSD for a Boxster S.

I am aware of the Quaife and probably think this is the best thing going, period. But since we get such great deals on parts from Porsche, i am wondering if there is an LSD off the shelf, maybe for some 997 model that can be used in the 986 S 6 speed gearbox? I looked in the PET and see nothing of the sort but I believe LSD is an option on some 997 models. If a diff exists, the question then becomes will it fit in the 986 transaxle?

Again, i think the Quaife is still the best thing going, i love the design of the unit, (ATB type) but at $1600 I am looking for an alternative that maybe a little cheaper.

Who has been down this road and what's available? Or is the Quaife the only real option, albeit a great one?

Do you really think Porsche will be cheaper?

Actually YES! (how crazy is that right!) Have you ever priced parts from Sunset? If not do yourself a favor, Porsche parts are cheaper from the dealer then china parts are for any Ford from Autozone.

I have spent at least $1000 this year there!

I went with the Quaife unit. Yesterday at an autocross it seem to hook up well. I am still able to break both rear tires loose on really sharp turns. I think guards units are only available with six speed tranny's?
