Can't believe that the fit is considered "reasonable" for the GTD by either VW for not designing GTD specific ones if the standard ones don't fit, or by the dealership fitting them. Strongly suspect that standard Golf rears would do the GTD, because it is not fitted anywhere near the side sill extensions that make GTI specifics front a necessity for the GTI and GTD, and rear diffuser for GTD is ery similar to, if not the same as standard Golf 7.
