it took a while for the parking lot to get completely cleaned up where i didnt mind crawling around. I started with just a basic air dam, but have some questions about maximizing its effectiveness.
I currently have it set up with 3 inches of ground clearance and just paralleling/contouring the lower end of the bumper. my first observation/appreciation for it was how quite the it is now at highway speed. There are few hills here so i can only do modified coasting measurements. I have shifted my coasting points to turnoffs on my usual route to/from work by about .2 miles
i haven't done any tufting tests so i don't know if i am creating too much wake to get the most out of the air dam. How far should it extend laterally to minimize wake and drag?
Pictures to come later.
