A spoiler slidably supported within the rear body is coupled to a forwardly extending gear rack. A compound gear is rotatably supported within the rear body and engages each gear rack such that movement in the forward direction of the rear spoiler causes a multiplied distance movement of the gear rack supporting the front body portion.
