Stupid me, relying on memory got it 'wrong' again!
It's 14-paragraphs, and it's for the SF90 Stradale Assetto Fiorano, hybrid supercar, an additional $56,000 option.

* The car delivers 859-pounds downforce at 155-mph.
* Both front and rear wings can be defeated as a drag reduction strategy.
* The rear wing breathes from above and below in normal driving.
* For downforce, an electrically-driven ' lower section ( a.k.a. the shut-off Gurney flap ) drops down to close off the flow underneath and create a totally new tail geometry.' Jonny Lieberman

Since drag and lift both vary as the square of the velocity, calculating what downforce the Ferrari would produce at 120-mph, would simply be a comparison between the square of 120, and 155, as a multiplier for 859.
