It's about how far the airflow gets pushed to the side. You want it to go just far enough to clear the front of the wheel and not so far as to extend the effectual frontal area of the car (via blown out airflow, apparently).

Thanks again,

Alright I'll try that, I'll cut two inches off of each spat. I have seen ones that are like that before. I'm hoping that there are actually doing something
