Using (or Not Using) PSM with the Cayman R

I've taken the CR to autocross a couple times, and will be taking it to the track for the first time this week.

So far, I've left PSM on, thinking that it's good to have a safety net. But I'm thinking that I should try leaving PSM off for autocross, so that I can really experience the handling of the car and learn car control. And I'm thinking that I should try turning off PSM at least part of the time on the track also, though of course the concern there is the higher risk that comes with more speed.

I'd appreciate opinions on whether to turn PSM off, as well as insights into when PSM kicks in and how the behavior of the car differs with and without PSM on.

Leave it on....go talk to the guys in the garage... You'll hear some interesting stories about the guys who turn it off in the neighborhood and wind up in some bodies front yard...
And this relates to the turbos.. Of course but still...
And then your asking about hpde insurance as well...
Ive done 12 track days in mine..the thought hasnt even crossed my mind to turn it off...

Although I did hear my rep said they tried to make this thing get out of control and the car held tough...

Now granite.. After 4 days at barber with the p driving school.. I'm also have what they said in the back of my head...

I will say this ... I've already tested the car... For fun... I know what my limits are with the car... And for my safety n the cars safety ... She's going to TPC at the end of the month...
I want more power... You'll see if your really grinding on it.. And you will be eventually...
You'll want more power down the straights.. Or least I do for personal reasons...

But I want the suspension package...stage 3...

No it's not a necessity... But my car.. Shes a track *****!!! Nothing more... She wants it as much as I want it... And when you start driving her hard.. Your gonna want it too!!!

Pay extra attention to the rear caliper's rubber piston boots (dust covers) when tracking your car with PSM on. I give them extra close inspection after a track day when swaping the track pads back to street pads. The PSM will get involved enough in the corners to keep the heat up in the caliper. And if your track has turns mostly in one direction, your inside rear caliper will get hot. It doesn't get enough air flow back there like the fronts do. Don't let the pads get too thin. And consider titanium shims or you will be melting the boots starting with the caliper's outside/lower piston.
The car is completely stock and has about 3K miles on it, and I'll be tracking it for the first time tomorrow. I'll be getting 2.5 hours of time actually on the track, so I'm thinking more than 100 laps. I assume I can take breaks whenever I want, so I could go for blocks of say 30 minutes, taking 25 minutes going hard on the track followed by 5 minutes to allow cooling off.

Some questions:

- What's your opinion on turning PSM off?

- Do you see any problems with running it on the track under the conditions I described?

- Anything special I should do to prepare the car?

Your comments regarding the brakes have me a bit concerned ...
