i never did install them:( i got the primed ones painted body color and wanted to go and actually figure out the true locations for them. but realized i was too lazy lol. i was doing it for appearance more or less personally. i still wasn't convinced that they would be that much of a game changer, since i don't do much highway driving and city streets only have so much distance to travel on:( but if you search on youtube there are a couple of how-tos on testing wind paths.
