I believe most track events require a yearly flush. I just had a track inspection done and there was a specific spot for the date.
Enjoy the day!

Ok I know I am going to get spanked with the "use search" on this. However I did. There is a lot of contradictory info about each topic, so hopefully having them all in one place will help future track day users like myself, easily access the info.
I have 20+ years of track day experience, however I have my first day coming up with a 991.1 GT3. I would GREATLY appreciate any current and past owners sharing their wisdom on the following:
South Florida Track Day. Warm Temps.
1. PDK Sport Button ON or OFF in Manual mode ?
2. Suspension Button ON or OFF ? (And if possible Why).
3. Suggested Starting Pressures for Cup 2 Tires.
4. Ideal operating temps for Cup 2's.
5. Anything else I SHOULD know, that I did not ask.
Thank you in advance for helping take any unnecessary anxiety out of an otherwise fun track day !!
Cheers

- I use the paddles because it's more connected and fun, and I like knowing and controlling when the shifts happen. If you put in auto, use PDK Sport.
- Firmer or stiffer damping depends on the track. Try both. Softer is better for soaking up heavy curbing. Stiffer is better if you find that the car is moving around too much, which for me only happens with bumpy braking zones. For most tracks, both modes work well.
- With Cup 2, don't start below 27 psi, and don't really lean on the tires hard until you're closer to 30. Hot, you want to be around 32-33.
- Use good brake fluid like SRF. Also use track pads, the OEM pads aren't good enough for an experienced driver. Avoid using ABS, because it will put too much heat in the brake system and make the pedal go soft even with SRF.
- Leave the PSM on. The limit for it to engage is high enough that it shouldn't intervene until you're way out of shape.
- Factory alignment is fine. No need to mess with cambers, etc.
- Bring extra motor oil to top off if needed.
- Have fun and be safe!

You won’t have to change back and forth but ideally the high boiling fluid is changed annually whereas the regular can be used twice as long. They don’t fall off a cliff either, but after a year or so just won’t have the ideal characteristics anymore.

There are several decent track pads available.
SRF is my brake fluid of choice. All other fluids are standard.
Don’t mess with aero on this car.

Outside of that, I would leave it alone.

Not exactly what you asked but also suggest consider driver development- coaching, and data/video. I use AIM but VBox is popular. Also the Garmin catalyst.

Minimum track essentials:
Tires: Cups 2's or Trofeos (don't run old tires)
Track pads (OEM are ok for 2 - 3 times a year)
High Temp brake fluid
Alignment
Safety: Hans Device if you're running a harness, Roll cage, Buckets seats or aftermarket seats (ie. Recaro, etc).
Leave all the systems on until you are very comfortable with the car
Coaching - very important - learn where to look/accelerate/brake, where to position the car, read what it's telling you, etc....
(Leave the ego at home and keep looking in your mirrors for faster cars).
Have fun!

Grant. Why do I see a lot of track driving in the states with the windows open? We are not allowed to have them open.

The theory is safety crews don’t have to break the window to access the car thus saving time. With the right tool is it saving that much time? 6 to one.
