Detroit Speed's Camber Eccentric Kit allows you to add alignment adjustment to the lower control arm on your 1965-1966 Mustang, 1960-1965 Falcon or Comet. This became a standard feature on 1967-1970 Mustangs, allowing for easier alignment adjustments. DSE also adds an octagon washer that allows 16 adjustment locations and eliminates any movement of alignment. Each shim is Black Anodized 6061 Aluminum, with Laser etched hole locations.
