I have no post to reference this, but seem to remember that the HDK added 75kg downforce to the 570S at 150mph

I read this a while back. They said within 20-30kg of GT2RS at 200KMH.

I do not understand your answer :)

you mean the 720s will be the same downforce like the Porsche GT2 RS less 20-30kg?

600lt has 100kg = 220lbs at 250km/h/155mph.

Yes that is what the post said. They don’t specify which configuration for the GT2RS. But they said at 200KMH the 720s makes about 20-30kg less than it. Depending on the configuration you look at could be anywhere from 400-500lbs all around for the 720s. 992 GT2RS makes around 750lbs total at 340KMH and with the wing in its highest angle of attack makes around 1000lbs total at the same 340KMH.
You could search figures on 650s as the 720s has 50% more than it.

From my calculation it should have about 400lbs of downforce all around at 300KMH. I used this as reference. Another member calculated the downforce for the 675lt.

you mean 400lbs (181kg) at 200km/h? Or 300km/h?

When 992 GT2RS makes around 750lbs total at 340KMH - does it mean it has 441lbs at 200km/h?
441lbs = 200kg at 200km/h

720S: 200kg less 25kg = 175kg at 200km/h
175kg = 385lbs at 200km/h
is that right?

yes sounds about right ... I remember sth around 200-220kg at 250kph for the 720s

main difference to the GT2rs is that the df is more or less permanent on the Porsche only changed with different settings of the screws on the wing while the 720s can significantly change the number with different angles on the active rear wing while accelerating, cornering or braking ... I don't know if the df is meant to be in normal high angle wing setting (active mode - aero on) or highest angle while braking ...

So, basically this entire thread is about bragging rights at coffee since the odds on spending any real time above 155 will be little to none. At least the cars aren't generating lift! :)

Well, that might be your case, but I have spent many miles at speeds above that range. I know of a few others on this board as well that have been up in those ranges for sustained periods of time.
