I understand PSM will always kick in if need be. I am not at all concerned that PSM may slow me down or hamper my laps times. What I am getting at is in the long long run will I become a better driver by starting the learning process with PSM off or on?
btw, I think I should mention that I am have your typical toxic male mix of overconficdence and lack of fear. But I know the club rules and my instructors will keep that in check. Just being honest about my shortcomings.
Much thanks!

When you read how a pro learns a track they start out extremely slow - by walking it. Then they drive slow and try to learn the lines. Then they accelerate a bit and slowly build up to their performance speeds.
I recommend that you leave the
PSM on. How it will manifest itself is by (perhaps) slowing you down a bit if you are a bit aggressive on the throttle coming out of a corner. That's a good thing to be slowed down at. We call it Please Save Me - it's not a bad thing at all.
The way our
PCA club teaches corners you brake linearly on the way into the corner, take your foot off the brake as you do the corner and don't get on the gas until you can see your way through the apex. This is seen as a safe way to start out.
PSM won't do much if you drive this way - again - it will only help and not hurt.
Finally there was a lawsuit (last year?) where someone had turned off the stability system on their car and then gotten into an accident. Turning off the stability system created additional liability for the local club and for the driver. Again - I would recommend leaving
PSM on.
My view is that I want to bring my car back without wrinkling the metal. I don't want a $5k re-alignment exercise to go through. I want to be a better driver and I want to learn to safely drive faster. I am more likely to accomplish all this with
PSM on.
There's people at the track who don't have
PSM (older vehicles) or who turn it off. It's a choice but I have an obvious bias.

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |
