Detroit Speed's Camber Eccentric Kit allows you to add alignment adjustment to the lower control arm on your 1964-1966 Mustang. 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. This kit can be used for 1964-1966 Mustangs.
