In this tutorial, we learn how to install a chin spoiler on a Ford Mustang. First, you will need to remove the four screws below the front bumper of the car. Now, remove the underneath section that is located just below the license plate. Drill holes inside the new spoiler, then reattach the sensor and put it back in place where the old chin spoiler was located. Make sure you replace any bolts that you took out in the beginning. You can use double sided tape to make sure the spoiler sticks, and then use a screwdriver and replace any loose screws.
