If a change or modification is not specifically authorized, it is not allowed. All repairs must comply with factory-authorized methods and procedures, or industry standard methods, as follows: If the manufacturer does not provide an appropriate method of repair, industry standard methods and procedures may be used. Such repairs may not result in a part or combination of parts that provides a performance advantage (e.g., significant change to weight, suspension control, power, etc.) as compared to the standard part(s). Competitors are strongly cautioned to use this allowance to make common-sense repairs only.

1. Wheel lug studs (e.g., length) and lug nuts may be changed.

2. Components which are normally expendable and considered replacement parts may be used provided they are essentially identical to the standard parts, used in the same location, and provide no performance benefit. Examples are:

A. Clutch and related components (excluding flywheel).

B. Hardware (nuts, bolts, clips, etc.).

3. Parts superseded by Ford® may be used.

4. These allowances are strictly to permit components to be replaced from alternate sources other than the original manufacturer. They should not be construed as an allowance to replace components with those which could be considered a “higher performance” alternative.

5. It is not permitted to use non-compliant parts even if they have been set to the manufacturer’s specifications.
