I am thinking about buying some 17" Racing Hart C5 (3 Piece) from someone on another car forum and was wondering if it is possible to tell whether or not they are real Racing Hart C5s. I was wondering this because the ones I was thinking about buying does not have the black "Racing Hart C5" logo on the spoke of the wheel that is show in this picture:



However I do know that the center cap says C5 on the wheel that I am about to buy. Also, i have seen some Racing Hart C2's have "Hart" or "C2" engraved/imprinted somewhere on the wheel. Is there anything similar to this that I can find on the C5's? Or anything I can look for to check to see if it is a real racing hart C5 wheel?
