They have a wing profile.
So they can create a force (but they must not).
There are two of those wings so the forces have a counter effect in a straight line.
But in a bend due to a special wing profile and a diagonal
angle of attack one profile produces more force than the other.
This force points to the inside of the bend and helps cornering.
Other than the force the front wing produces is this wing producing
the centripedal-force directly and not over the tires.
So you can use harder tires
and have although good cornering ability.
(This is my theory)
