Well a guy on this site mentioned that the wings west touring car wing sucks as is flimsy. Said something about the side fins flexing at high speeds and that it seems to be made out of cardboard. hehe The JSP one looks a little thicker but i'm not sure. They also come in different lengths. Any one care to comment on there JSP wing or WIngs west wing. The pro's and con's of them. Also which length is the best.
