thanks, I made mistake of putting in neutral, which resulted in rolling. Not likely going to be an issue very often but thought I would ask. Thanks for info.

1 ways to put it in park!

1) With the transmission in the N position, just turn off the car by pressing the Start/Stope Engine button once, that shuts off the engine, then press it again and you see it goes from N to P. Magic!

2) An easier way, keep the car in the 1st gear, now when you press the Start/Stop engine button once only, you see it go into Park straight away.

a slower cool down lap so you don't have to use your brakes much?

To put the car in Park, you simply move the shifter to the right until 'D' shows as the selected gear, then hit the start/stop button and P is engaged. Always use the handbrake by first by applying brakes and then put car in Neutral.

to most of you. You are not answering the OP's question .

First, it is not possible to put the DCT back in Park after it was put in S or D when the engine is running.

Second, there is no real issue at using the parking brake on the M3/4 after a track session. On the F8X, as was also the case on M3s before it, the parking brake is handled by a separate drum brake system inside the disc hub. The shoes are not used when on track, so they do not get hot. There is therefore no risk of making a pad imprint on the discs when applying the parking brake. I've been using the parking brakes on all my ///M after track sessions for over 16 years at the rate of 16~20 track days per year and never had an issue.

Third, the cooling system of the F8X is very well engineered. There is no need to leave the engine running when you park in the paddock after a session. Look at the coolant needle once you are in the paddock, you'll see the engine temperature is right at nominal. Further, the turbo cooling is handled by a separate system with its own electric water pump. When you shut down the engine, if the ECU deems necessary, it will circulate water through the turbos and keep the radiator fan running until properly cooled.

As a tidbit, right after your next track session, pop the hood and touch the intercooler. You'll be amazed .
