The Quaife lock will definitely help in that scenario.
I want a disc type lock because it will also help to stabilize the car under braking and I can rotate the car with the brake too.
I'd say for me the benefits of the lock are 60% acceleration and 40% braking.

I believe OS Giken (osgiken.net) makes a well regarded locking diff for our cars. Guard does go to market with their products for our cars through BGB Motorports as stated above (teambgb.com). Ask for John Tecce if you call them. He is very knowledgable and helpful. He also builds some bad *** Caymans as you'll see on the website. Cheers.

Well, I called Guard a month ago, they first offered a torque biasing differential but I insisted on getting a proper limited slip (disc type) differential.
They promised to get back to me, no word yet and no response to my e-mails nor can I reach them through phone...
Maybe they don't have a suitable product for me or they are just too busy other customers...?
It seems Cargraphic has a disc type LSD for the non-GT/turbo 997. They even offer different ramps 40/60, 50/60, 50/60, 60/80%.
I think I will go with their unit with 40/60% locking, which is quite a nice compromise for a mostly street car.

Here's me on Saturday driving the **** out of the 997 on and cussing at the open diff and the crappy/greasy street tires..

The car is quite difficult to control with the open diff...really. My 993 is MUCH easier to drive on the limit.

Interesting reading this thread...
Can some one here help me understand whether in general, 997.2 Carrera S's left the factory with no LSD installed (I thought previous that all 997.2 were factory equipped with them as standard equipment)... unless it was specifically ordered as part of a specific option package )e.g. Sport PASM)?
I bought my CS second hand, can I still find out from Porsche the specific option list via the car's VIN to see if I my car has a factory supplied LSD?
Thanks in advance...

According to the Guard website:
http://www.guardtransmissionllc.com/...differentials/
they do have a version of their LSD for the 997, but only in a Pro flavor.
Pro – High Strength, hardened 4340 Chromoly billet, 8620 cover, multi disc, Pro+ is 100% 8620 billet
Club – 1045 Billet body, still far stronger than any Porsche or ZF LSD. All of our LSDs come standard with 4 friction discs, however, 6 or 8 disc versions are also available.

Stock Porsche LSD that comes on SPASM or as an option with PASM only on the 2009-212 cars only lasts 5 or so track day or 10k miles of street driving. Not sure why Porsche doesn't really fit a proper LSD as an option in these cars. The dealer also can not repair the stock Porsche LSD.
So...Guards is really the way to go. They have 997 PDK versions on display at the Sebring 48hrs. IF I was keeping my GTS and not selling it this would be the replacement LSD I would buy.
