Custom rear spoiler for the Missile

the trunk lid thing is actully a myth
"Two stories explain the rear spoiler. The common idea is that it's three feet tall so the trunk can open. However, it could have simply been mounted on the trunk in the production cars. An interview with the engineers at Chrysler, long ago, included a comment to the effect that as the numbers kept getting better as they raised the spoiler, until it was three feet off the car, that's where they left it."



I understand about the wings having to be in the airstream. But from what I've read the main reason the wings were as tall as they were on the Daytona and the Superbird was because they had to be sold to the public & if they were much lower the trunk lid wouldn't open. I think the wind tunnel testing had shown they were effective at a shorter height but they were raised for trunk access. I do agree with the part about the vertical stabilizer effect.
