That's not what he said in the last video? It's moderate aero won't do much on a heavy car as you need serious aero to see a benefit.

That's very different than aero doesn't benefit heavy cars.
Its complicated and I don't quite understand all of it. But....

If you also study tires, you can see that loading up the tires provide more grip up to a point, from which the rubber give up.

So if you have heavy car, and you load up the tires on top of that in a high speed turn (g-forces) and on top of that add downforce, you are not necessarily going to have more grip.

Now, if you have a light car, that cannot load up the tires by shir g-forces, aero will replace the weight of the heavy car and you gain traction.
