Go with what you want....but IMHO i think it looks horrible on our cars. I only like it if you have the rest of the saleen body kit..which our cars dont. That is the main reason they built the wing to look like that, it flows very well on the saleen cars.
I think the one piece looks good when a cowl hood is used. The three piece looks good with the complete Saleen body kit. Other than that I would say keep the original, but its your car. If you like the look do it.
I used to like them alot, and still do on the GT's. I had a one piece one for my car that I never put on and finally sold. think they look a little off on the cobras
I feel they don't flow with the lines of the car at all. Too square and rigid. On the saleen mustangs they look fine because they match the flow of the other body pieces on the car. Its up to you tho.
