I believe the OEM spat design is correct. Without increasing the front area and being set inward it moves some air from under to the outside. The air moves out at maybe a 60 degree angle, so it doesn't have to go to the outside edge of the tire. I wouldn't change it by more than a 1/2 in any direction.
