Ok, so when a car turns, the tires provide the acceleration pointing toward the center of the turn. If for some reason, I put a spoiler on my car with two rectanglular pieces, one on each side that are tilted, to the left, mocking an airplane rudder, thus when the wind has contact with them, there is a force with a component backwards and to the right. If my car is turning to the right with this spoiler system, this will help with the turn and take some of the force off the tires, or even allow the car to take the turn faster as now the tires can have the same maximum component of before and then the extra from te spoiler (correct me if I am wrong). Also, with this system, how do I ensure that yaw still occurs around the proper side and the car rotates arround a corner? Thanks for the help.
