The Ducktail Spoiler is Designed and Engineered by CDC. This blow molded ABS spoiler is a three piece spoiler, which is lightweight and requires no trunk strut adjustments. The '05-08 Mustang Duck Tail Spoiler will hard mount to the vehicle via Bolts and/or Acrylic Bonding Tape to increase durability and long term proper fitment. The spoiler is available with or without pony logo (an indention has been added to the with logo spoilers to provide a flush appearance), in all factory colors and unpainted. To simplify the installation process, order your Mustang with the Spoiler DELETE option. If you have the factory spoiler you can order CDC?s optional stock spoiler hole delete kit. The Nifty Hole Filler Set eliminates the need to repaint the trunk while giving additional appeal to the Ducktail Spoiler. CDC designed the Ducktail spoiler without the CHMSL to meet their true vintage design goals, but CDC understands that some customers wish to have the optional 3rd brake light so they created a system that does not intrude on the design efforts of the spoiler. This optional 3rd light mounts inside rear window. This 15.6? LED light adds a high mount high tech look when brake is applied and is otherwise invisible.
