        3 2019 Bullitt - must9350 Installation Time: Afternoon

        Gt350r style wing

        Very nice looking piece, it looks great on my 2019 bullitt mustang, but is too flimsy, it shakes really bad from 55 mph and higher.

        Piece of junk

        Piece of junk. This thing was the biggest piece of junk I’ve ever ordered. Absolutely no instructions. Horrible fitment. And vibrates at anything over 45 miles an hour. And it’s not like I can take it off and send it back because now I have six holes in my decklid. Worst purchase ever.
