I have a CPO 2014 911 with clear bra on bumper, full hood, front fenders and mirror installed by previous owner. It looks like a precut kit not sure which brand and to my untrained eye looks like a perfect install. At highway speeds I had a whistle which I traced to drivers mirror. I placed Blue painters tape on leading edge and sound disappeared. I do NOT see anything wrong with install but needless to say the sound is there. I would like to have a permanant solution. Should take a heat gun (blow dryer) to the leading edge. Can I buy just the drivers mirror piece or trace old pattern on a bulk roll and cut it myself(off the car) and install myself it is a very small piece and shouldnt be to difficult or find an local installer to replace just that piece. Once again I cannot see what might be causing this whistle but it is there and is gone with tape on it. No whistle from passenger side btw. All input appreciated.
