When mounting a Fanatec Rim to a direct-drive wheel this adapter is needed to attach the Fanatec 52mm bolt circle to the 70mm standard diameter found on most direct-drive motors. This adapter will also let you fit our NRG quick release or any other 70mm quick release. The adapter includes screws to mount the adapter to the direct-drive Mini-Mite, SimSteering or OSW motors or the NRG quick release. Some screws from the Fanatec rim must be re-used. This adapter will not fit the McLaren rim.
