modified before the start of each new season provided that:
a. The layout of the Driveline Components, Gear-Change components and Auxiliary
Components is unchanged, except for a translation, as a group, in X.
b. The part of the case considered as Cassette remains unchanged, except for a translation
in X.
Approval of the modification must be granted by the FIA.
The Gearbox, as defined in Article 9.1.1, is classified as TRC.
