What did you do to your 996 today?

Yet my 2001 does not.

No PSM on my 02.

My '03 Targa has PSM. It works great when you are hydroplaning.

Hmm, non-PSM .2 cars might be more rare than I thought. According to a post in an earlier thread:

Standard on ALL AWD 996s (which includes turbos), optional on C2s starting in model year 2000 (along with the switch to e-throttle on all 996 cars), not available on the GT2/3. I believe it was also standard on the 40th anniversary cars, albeit with revised tuning and the LSD. Prior to 2000, 996s were cable throttle and had a more primitive traction control system.

But I purposely didn't want PSM because i wanted to learn how to drive it on the track. However, I assumed it had a LSD after looking at a few 996.1s previous to buying my 996.2 and found out it didn't. No big deal, I then put on a Guard LSD and have been living happily ever after with a great handling car that you can easily control in varying conditions.

It may have to do with a majority of 996.2 cars not having a LSD, so PSM was supposed to save the day.

996.2 Tip here with neither LSD or PSM, and it does that characteristic nervousness when trail braking which makes me sad (my hoodrat BMW has a working LSD and can even use 964 clutches). Does Guard do semi-custom applications? I saw they have "coming soon" Tiptronic applications but I doubt it's 996, unless we share a diff with 997.1 or something.
About 15 years ago my indy sent my diff to Guard and they sent it back with the LSD in it. At that time they had a program. I hear they still do it and I also hear they don't do it anymore. Best thing to do is give them a call.
I understand that today their are a couple more providers of quality that you can choose from with varying internal designs.
I do have to say that the Guard has been performed beautifully. My indy just rebuilt it 2 years ago when they dropped the engine and were refreshing everything for me. But I had put on quite a few laps on Hoosiers over its history so a rebuild was inevitable.

Oh awesome, I should read up in that section. Any chance a Turbo 722.6 uses the same diff as an M96 722.6 though

Performance advantage. Even with the power being sent to the front with an AWD system, the wheel with slip will still get more power sent to it with an open diff.

Hi, also have a question about this. I thought all Turbos came with AWD, so an LSD seems to be somewhat redundant. Or would the LSD combined with AWD still create a performance advantage in some way? Or is this for the folks who will disconnect the front wheel drive? Thanks.
Removing the AWD with the Tip is less wonderful without an LSD, you're stuck with one wheel drive. So they're trying to get the LSD mostly for those that want to go RWD. If a LSD for Tip had been available I might not have done the manual swap.
