The front spoiler and foglights went on with the front bumper on the car. If you have the time to remove the bumper and install the pieces, especially the foglights, it will be much easier. I duct-taped it in place and drilled the holes needed to mount it once I knew it was in the right spot. Tape the sides flush to the bumper cover and make sure both sides are uniform. Don’t be intimidated by this operation. Measure twice, drill once. Once you have the holes drilled, use the provided hardware to permanently attach the spoiler.
