Suggestion
Disconnecting (or putting a switch on the ground wire) of the actual yaw sensor.
Leading evidence: 'Disconnect (or putting a switch' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Disconnect (or putting a switch' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
I've also seen some references to disconnecting the brake switch (your picture above?), but I think the consensus was that negatively affected ABS.
Disconnect sensor below did disable psm and abs still worked

Similarly, there are some reports that disconnecting the yaw sensor interferes with PASM (Porsche Active Suspension, not PSM) and Sports-mode (Sports Chrono option) on later 997/987 cars.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

UPDATE:
Disconnecting the sensor below did disable PSM and ABS still worked. I was able to back the car into corners at will and engage ABS. You do get 2 warning lights at start up and every ~15min for PSM failure and brake fluid sensor. It's annoying but not that bad.

I have a lovely 2002 c2 I just picked up. Against my better judgement and initial intentions, I plan to do some track time with it now. Can Anyone please verify this is how I completely defeat the PSM and that it wont effect the ABS? I unplugged the clip going to the yellow sensor on the side of the brake fluid reservoir. I posted this in the Racing and Comp forum too.
Thanks!

I've seen reference to two successful methods for fully disabling PSM so it doesn't turn itself back on during certain braking events:
Disconnecting (or putting a switch on the ground wire) of the actual yaw sensor.
Interrupting power to the actual PSM computer by putting a switch on the ground wire for the module.
I've also seen some references to disconnecting the brake switch (your picture above?), but I think the consensus was that negatively affected ABS. Similarly, there are some reports that disconnecting the yaw sensor interferes with PASM (Porsche Active Suspension, not PSM) and Sports-mode (Sports Chrono option) on later 997/987 cars.
Planet9 (mostly Cayman and Boxster Forum) seems to have lots of track guys discussing this.

Let us know what you figure out...
Nothing to add on the PSM...But if that pic is of your car, you might want to drain some of that brake fluid out. The level should not go higher than the tip of the arrow. Otherwise you will have fluid all over the inside of your frunk before you know it.
With respect to the brake reservoir best to cover top with a rag and rubberband it. Like another one mentioned brake fluid level to high. Even at suggested level it still weeps abit if u track. As far as deactivating psm and keeping abs maybe post in the racing forum as well. Mike
Also that pos cover for brake reservoir don't try to over titen. Very easy to strip pos plastic threads- ask me how I know. Not a great seal once u strip the threads. Mike
The "sensor below" is ...
er, never mind, the original post was actully quite clear. (Oops. There should be a way to delete posts and not just edit them, no?)
