I decided to do this as it seems to help others who get higher mpg. It was pretty straight forward. The results seem to help better at lower vs highway speeds. I know the edge of the mirror by the lamp lens is a ridge to induce a vortex to help with aero.
I also added a mirror to my rear view mirror called the lane changer. Its like a big curved mirror to see out the windows of your vehicle.
