I think we are, like the wheels in question, going round in circles. From not only my post but from the others, we took your request to be..... would the 15" x 5 wheels fit and look OK on a Spider. It now appears that you want the visual reassurance of a photograph for aesthetic reasons I presume. May I ask what is behind this request? If you are at all concerned about aesthetics and proportion then stick with the 14" wheels and, by all means, go with the GTA style rims.
