ZDan, I understand any RC related equations become useless when it is very near the ground plane. That doesn't change the fact that when it (or the FAP if you prefer) passes back and forth above and below the ground plane your jacking forces will be constantly reversing direction. That isn't going to be good for stability at the limit of tire adhesion unless you have minuscule jacking forces to begin with. I don't know what typical jacking forces are for this car.
