Didnt know where to put this but I think the Teg forum is great... either way got a WINGS WEST SUPRA STYLE W/ LED spoiler off ebay the other day and really wish I could know if its authentic or not. Theres SUPRA STYLE branded on the spoiler but other than that theres nothing else on it. And how can I tell whats the material its made out of? Its quite stiff and heavy.
