I happened to notice deep in an M web site, that the speed delimiting can be done retroactively:

https://www.bmw-m.com/en/topics/acce.../packages.html

"With the M Driver's Package, the maximum speed of the BMW M5 Sedan boosted to 305 km/h. The Driver's Package can be ordered with the purchase of your new car, but can also be retrofitted at anytime."

Has anyone done this through BMW after purchase? (I read that someone had done it with an external tuner.)

I heard it’s extremely difficult to do, which is why I checked the M performance box when I ordered mine. Not to say it cannot be done.

very curious on this too, as this part of the world, whatever cars the dealers received is what is available, no such thing as choosing options and spec'ing out a car. Would love to have the car delimited

Found this on internet:

And I believe they are not the only ones that can delimit your car

Given that the M website clearly states that the delimiter can be retrofitted, I'm a little surprised to have to go all cloak and dagger to get this done - can't the BMW dealer do this?

It’s limited to 305 KPH or 189 MPH. If it wasn’t restricted could easily break 200 MPH

I suppose so, but I think the tires may reach breaking point at such speeds, at least the stock ones.
