I am the second owner of a 997.2 Carrera S Cab. I was looking at the build sheet and never saw limited slip listed as an option or standard feature.

My car has PSM, does it therefore have limited slip standard as part of the feature ?

DGrayling

I believe the limited slip rear end only comes standard with the Sport PASM option.
option "030 - PASM sports chassis - 20mm"

It's an option so if it's not listed in your build sheet I doubt you have it. just get a guards unit.

Comes included with the Sport Suspension or as a standalone option. Not included with PSM.

So i want to make sure that I understand this clearly then. If I have the button near the gear shift that says shows an image of a shock absorber then does my car therefore have sport option- then I also therefore have limited slip ?

ltcjmramos

Nope. There is no button for the Sport Suspension. It is an option that is "just" a more aggressive suspension.

I assume you have PASM. On my PDK-equipped GTS, I have three buttons, Sport, Sport+, and PASM (the shock absorber one), in that order. When all are off (no lights), throttle map and suspension are "Normal." Press Sport, throttle map is more aggressive, shock absorber button lights up indicating PASM is active. Hit Sport+, and an even more agressive throttle map is invoked. I know in Sport I can turn PASM off to have a more aggressive throttle map, but a normal suspension.

Check your Owner's Manual. In mine, it's pg 57.

Also, for your build sheet, go here, add your VIN # after the = sign

That's the PASM button. The Sport Chrono buttons will say "SPORT" and SPORT+". The button with a pair of exhaust tips is PSE. Sport suspension has no button, it's just there if you have that option (ie, you would not have a PASM button). Same with LSD- there's no button; if you have it, it's just there.

I have always thought that all 997.2 911's have a limited slip rear differential as standard equipment... so if I have this right, now reading this thread, that actually VERY FEW 997.2's do... is that correct???

ltcjmramos

Correct, specific extra-cost option.

No worries though, if you wanted a functioning LSD for tracking (not much other application for it given the rear-engine weight bias unless your breaking many laws hahaha) you'd buy a guard. Even the guys with GT3s apparently get good use out of their stock LSD for maybe 2 track sessions before needing to replace the internals etc.

At least that is what everyone has said.

kcheves

If you have it as a separate option, it is option code 220. $950 when ordered on my 2009.

A mechanical locking differential is standard on the GTS when you order the sport chrono and SPASM packages is it not?

ltcjmramos

Yes, Sport Suspension includes the LSD, option P17 on my build sheet. PASM is a completely separate option. My PASM came as part of Sport Chrono Plus, option 640.

I ran about 10 track days before needing to replace the LSD on my ex-6GT3. I did replace it with a Guards unit.
