Probably not what you want to hear, but I'll give my .02 anyway. I just recently tracked my 2021 Scat Pack A8 with the dynamics package (adaptive suspension, 275s). And when I say track, I mean I brought it to the drag strip once in Maryland, made a couple of passes, and did about a total of 20 laps around Dominion Raceway on two different days during a Track Attack, which is like a spirited ride around the track not trying to set records. My best advice to you is to bring you car to the track first without doing any modifications. I know the impulse is there to get it all decked out but trust me on this. Bring as is to the track. Learn your driving style. You'll probably feel like you need different tires or stiffer suspension. Whatever it is it's best to try out what you have and then make mods so you can see a different the next time you go back.
For drag I put the pack tires to around 25 psi and fronts up to 40. Suspension in street. You can try launch control if you have it, but will likely spin the tires. Try a few passes and see how you do. Transmission and so forth I tried sport and track, I actually think street may be best so you don't blow out the tires.
For the track (road course) 32 psi squared. Have a good helmet in case they are required, depends on what you're doing. If you have it, put it in track mode for steering, suspension, and trans. I set traction to street. You'll want it to help you out in the beginning. Work on proper sitting posture, 9 and 3 on the wheel and smooth inputs.
Just give whatever it is a try and then add stuff later. Once you tracked it, things will just click and it will give you more satisfaction the next time you bring it modded.
