The car is bone-stock except for Toyo RA1 tires. It has not even had a proper alignment, so there is almost no negative camber in the wheels. That will be my next move, since the Toyo's really need at least 1.5 to 3 degrees of negative camber to be effective. I'm running stock Cayman S wheels.
My biggest take-away how much better (more predictable and faster) the car felt with PSM off. After years tracking a 944 that had no stability control (not even ABS), I found it really unnerving to have the PSM doing it's little computer-aided thing on the track. It keeps the car stable, for sure, but at the track it has the effect of slowing the car down and resisting all the driver's mid-corner inputs. It keeps the car from rotating under trail-braking, lift throttle, etc... which is not a good thing if you need the car to rotate more in order to get all the way to an apex (for example). PSM is off in the video. The car is much more fun (predictable, adjustable and fast) with PSM off. It did not feel unsafe or unstable at all (on a dry track) with PSM off.
Other notes: 1) PASM Sport vs Normal. Less noticeable difference between the two on the track than on the street. Sport is moderately bumpier... but I didn't sense any major improvement (or change) in turn-in, mid-corner grip, adjustability between the two settings. Both are very nice. 2) Sport Chrono: I cannot tell if this makes any difference other than making the throttle pedal more sensitive. I ran with it on most of the time, but when you are really braking hard, the brake pedal sinks so low that it would be easier to heel-and-toe with the regular throttle sensitivity instead of the Sport Chrono mode. 3) Brake pedal... I learned that after the pedal starts pulsing (like ABS) you need to keep pressing harder and deeper in order to reach maximum deceleration. The "feedback" pulsing from the pedal comes on too early (IMHO). Learn to ignore the pulsing.
What a fun way to spend the weekend.
-Q
PASM - Porsche Active Suspension Management
This active damping system offers continuous adjustment of individual damping forces based on current road conditions and driving style.
The driver can choose from two setup modes, ‘Normal’ and ‘Sport’, using a separate ‘damper’ button on the center console. ‘Normal’ mode is designed for general road driving and circuits with uneven tarmac. ‘Sport’ mode is intended for smoother track surfaces, where the harder settings help eliminate pitch and roll.
In either mode, PASM continuously evaluates the current conditions while automatically selecting the corresponding damper rates from the respective set of mapped values.
A range of sensors are used to monitor the movement of the body under acceleration, braking and cornering maneuvers, as well as on poor road surfaces. The PASM control unit then evaluates this data and modifies the damping force on each individual wheel in accordance with the selected mode. The result is a significant reduction in body movement as well as a better grip on the road.
For example: if ‘Sport’ mode is selected, the suspension is automatically set to a harder damper rating. If the quality of the track surface falls below a certain threshold, the system immediately changes to a softer rating within the ‘Sport’ setup range. When the quality of the tarmac improves once more, PASM automatically returns to the original, harder rating.

Sport Chrono and Chrono Plus
This optional package is a valuable addition for trackday use. Available in conjunction with the CDR-24 CD radio, it includes a swivel-mounted analog and digital timer unit which is centrally located on the dashboard. All functions are easily accessible via the control stalk for the on-board computer. Analog dials measure hours, minutes and seconds, while a separate digital field displays whole seconds, tenths and one hundredths of a second. A second digital display runs in parallel in the instrument cluster. Click this Link to visit the FAQ entry for Sport Chrono.
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.

Reason: Too much info in YouTube link. Just need Video ID.

Awesome video - thanks for sharing Q! One of the best Cayman in car video's I've seen! I can feel you throttle steering through some of those corners.
Florida is flatter than the chests of the girls in my 6th grade class I don't know what the hell I'd do when faced with a hill on a race track! ...Sebring is "home" - no hills there. I guess point the wheels straight and hope all four wheels grip at the same time on other side.

I've got just over -1 degree in my car when I last had it aligned. I'm not sure how much more we can get out of the the stock configuration. Recently, I've begun thinking about GT3 control arms so that I'll have the room to dial in 2 or more degrees at the track. ....the thought process on that one is still evolving.

This has been one of my biggest "gripes" with the "Sport Chrono is faster" guys. On the track, I want to modulate the pedal, throttle steer and gently feed in power on corner exit. I want a "long" pedal - not a throttle with a computer controled hair trigger.

Ditto!
What pads are you running? Doubtful you're using a stock pad with RA/1's. I'm running Pagid yellow and like what I've seen so far. No brake fade. What about fluid? Did you flush the OEM stuff and move to a high-temp fluid?

Fantastic times! And thanks for sharing that video You'll be seeing a white shop car out there (slightly modded heh) or rather we'll be seeing the rear end of yours

Thanks for the suggestions on brake pads guys. Right now the car has the stock pads in it. I used to use Pagid Oranges in my 944, and then switched to Pagid "Blacks" (I can't remember the compound #'s). Even the brake fluid is stock, although I did bleed a bit out of each corner prior to the event because I could tell there was some air in the system (sure enough a few bubbles came out). I plan to fully flush the system with ATE superblue after work one night this week. That factory fluid looked a little weird (as if it had little white fish-food flakes floating in it). So I look forward to getting the ATE juice in there.
I am sad to hear the stock suspension will only adjust out to -1.0 degrees of camber. Oh well, whatever amount of negative I can get will be better than what I have now.
Drvreg: I will take a pic of my camera set-up and post it when I get a chance. It's a Canon Elura 100 MiniDV camcorder on a i/o port mount attached to a DMC harness bar. A Canon wide angle lens adapter is screwed onto the front of the camcorder (I think it's 0.7x or something). That's the only way to get the angle wide enough to see the whole windscreen and your hands. Also, to avoid the wind noise, I wrap an external microphone in a towel and put it in the storage bin behind the driver's seat with the lid closed (and turn off the camera's built-in mic).
Mooty: Didn't you used to run 2:05's or something like that at TH? What's your magic? I know you had Motons, but are those just shocks? Or was yours a full coil-over set up? How much camber were your running? Spring rates? I am still getting used to the softness of this car and I'd be curious to hear your thoughts. Thanks.
Sharkster: Mine's white too! So I guess I won't be the only CS out there with the secret 0.07 ounce weight advantage from the lighter paint. Sheesh!
Best to all,
Q

Great video OH do I miss California ditto the FL quote, great reviews on the PASM and Sport Chrono options i am glad I did not send the xtra $ on them
