Seems like you guys aren't against cobra cloning lol
No one has a problem with Cobra body parts. But most have a problem with putting Cobra badges on a GT. It doesn't matter what you do to your car it will always be a GT with a GT VIN number.
I think a balanced look is important. I've seen very aggressive hoods and front bumpers on otherwise stock cars. They look like they have a thoroughbred front and a donkey rear. Not a good look.
I went a different way with my car but since you already have a Cobra hood then I'd suggest:
...99-01 Cobra front bumper cover. I like it a lot better than the 03-04. I'm not really a fan of the Roush front bumper cover. I like the Saleen front bumper for a more aggressive look but I really hate the Saleen rear wing. I think the Roush Stage 3 wing would look good with the Saleen front bumper cover.
...Stock side skirts and side scoops. I don't think it worth the money to change them.
... With the stock or 99-01 Cobra front bumper cover I like the 99-00 rear wing moved back 2". I believe that is what is in the AM picture you posted. You could probably pick that up cheap at a salvage yard. I do not like the duck tail or shaved wing look.
...Stock rear bumper cover. I really don't care for the 03-04 Cobra, Roush or Saleen rear bumper covers. The 2001 Cobra is OK but not worth the cost and with it you'd have to shave the letters.
P.S. I wanted subtle changes for my car so I went with small cowl, stock front bumper, Mach 1 grill delete and front wing, and the stock rear wing moved back 2". The only thing else I might do is to shave the side scoops.
