My car's character changes totally at speeds well under some of those mentioned here. Planted? More like lowered onto rails. And this with no wing, spoiler, or control surface liberated from a salvaged airliner. Clearly, this is a function of a well-engineered suspension system and slippery silhouette which creates "road-hugging" aerodynamic force by design.
Perhaps the cross-section of the factory wing does provide a bit of "negative lift" at high speeds, but you'd likely get more downforce on the rear wheels (without the drag) by topping-off your gas tank.
Or do what I do: Keep a couple hundred pounds' worth of gear in the trunk.
