The new original Donkervoort central wheel hub cover seems to be lost quite frequently during harsh driving conditions. Not being cheap, it is better to prevent them from coming loose. Drill a 2.4 max 2.5 mm hole on the location as shown. Use drill oil. Then cut 3 mm wire inside the hole and mount a 3 mm mounting screw as shown. Use a Dremel to cut out a spot inside the rim which can take the mounting screw. This needs to be mounted with some Loctite. Please make sure when mounting into the wheel, that the surface needs to be flat, so it will fit the wheel hub easily.
