The rear spoiler extension is suitable for MK4 Focus ST-Line models, with one side of the spoiler extension gloss black and the other is textured matte with an engraved Flow Designs logo. It can be installed gloss side up or matte side up, depending on your personal taste, with darkened hardware included for a clean overall look once installed.
