This definition does not allow the updating or backdating of parts.

Alternatively, it may be measured from the inside of one wheel at the hub centerline height to the outside of the other wheel, then conversely from the outside of the first wheel at hub centerline to the inside of the second wheel. The two dimensions obtained are to be added together and divided by two to obtain the average. Measurements to be taken at both front and rear of the wheels and averaged to compensate for toe in/out. Wheel rim width shall be measured at the base of the bead seat.

    12.6 Open and Closed Cars

    An open car is a convertible (with or without a full windshield), a targa top-type car with less than a full windshield, or a t-top type car with less than a full windshield.
