I added a Carrera tail and front lip and could immediately feel the stability differences, but was thinking to shed some weight a fiberglass decklid with Duck would be the best compromise of weight loss with only minimal downforce loss.
Anyone know the drag numbers for each?

As far as I know I originally posted that graph years ago. It is from a fellow by the name of Robert White, he did an engineering internship at Weissach in 1977 and did a presentation on it at the Warbonnet, it was later reproduced in Pano on several occasions. I believe that Frere also published the same graph, I'm sure they both got it from the same source. There is an accompanying graph for the front end too
