This is actually mine.
Its a far away shot so I just posted those two closer ones in the first post. It does have the curved spoiled and not the flat one that came on the 01-04. The only difference is that i moved it back from the stock location so it hangs off the end of the trunk. For reference, the more pixelated Mustang I posted has the curved wing in the stock location. But thats neither here nor there. The wing could go if it helps aerodynamics.
Another thing, I have no idea how people here are doing those layover shots with the ideal angle. So Im unsure how far or close my body is to being near that perfect curve.
