Every owner has to find his own comfort level, of course, but I wouldn't worry about that. While it's arguably true that LeMans stripes are currently most closely associated with the GT500, they are an iconic design that have been used on LOTS of cars down through the years ... Shelby Cobras, Ford GTs, Corvettes, Miatas, Mini Coopers, even Dodge and Ford pickups. And on lots and lots of Mustangs, of every year and specification. Phony Shelby badging is one thing, wide stripes that don't say anything about "Shelby" or "Cobra" or "GT500" are another. If you like the look of LeMans stripes and want them on your car, go for it.
Good point, Allez. I hadn't thought of it that way and thanks for bringing it to my attention
