Design 911 sells parts, so that's likely why they are blocked.

You could get PSM on the 986, it was optional. All 987s have it standard.
Sport Chrono (the dash clock) makes "off" closer to "really off" for PSM on the 987. It's always at least a little on.
PASM is the e-shocks. Adaptive in real time, not a crappy two-mode like some 90s cars. PASM on a 987 also gets you 10mm lower ride height.

Top left button around the radio on the 986 with either be a blank or "PSM off" depending on if the car has it.
987.1/987.2 has the clock and a "sport" button if it has sport chrono.
987.1/987.2 has a button with a little picture of a shock if it has PASM.

My Civic Si has adaptive dampers. It's the ZF sourced CDC system so it's a little different than the Bilstein system Porsche uses. But the capabilities and effect are pretty darned impressive on a $25k car.

Unfortunately, a lot is lost on the layman. They hit a switch and they want the ride to toggle perceptibly between stiff and soft and they think that's it. In reality, the car is working very hard to take data from accelerometers, height sensors, yaw sensors, steering angle sensors, and other inputs and adjusting each shock individually at 100 times per second (give or take.) The real effect is limited only by the coding of the module. Enhanced pitch and roll rate control, stabilization or enhanced maneuverability in transition, improved launch and braking, enhanced stability in emergency maneuvers, etc. The stuff they can do with this tech is amazing.

Back to my lowly Civic, the ZF CDC system on that doesn't have height sensors as a cost cut. Instead it interpolates suspension deflection from accelerometers in addition to the slew of additional sensors on the car. Yet it has a tangible ability to "fix" dynamic issues in real time, something even the fanciest-of-pants race Ohilns or Penske shock can't do.

TL;DR adaptive shocks (PASM on a Porsche) are one of those tech leaps that the function itself is nearly imperceptible to most, but makes a car incrementally that much faster, easier to drive, more comfortable, and more effective in more situations.

Can you tell this is a topic I'm interested in?
