Installed new CDC Chin Spoiler today. Love the way it looks. Keeping it matt-black, to match the rocker panels and rear valence. Install was pretty easy, with the exception of two really hard-to-access downward facing screws. Quality of piece is excellent. Shipping was fast. Price was good. Fit is good, with small gaps on the sides where it is not totally flush with the body.
For my 2011 Mustang GT. Shipping was super fast. Product quality is excellent. Fit is good. Installation takes 2-3 hours, and it is intermediate level - primarily because most of the dismantle/install is done on your back (if you don't have a lift or ramps). Good price, I'm very happy overall.
