Thanks for the info on Biomimicry. I'm not trying to complain or anything but the CAD software I use (Inventor) really does not enjoy making waves.

1. That was one of the very first things I did.
2. I sort of have that, there isn't really a "standard" rear spoiler but I could certainly test the more popular ones like for instance
this one is the same type of spoiler our racecar had before we slapped a huge superbird style wing to it (story for a different time).
3. I don't have a 240z, I wish. There was I think a spoiler that come with the civic model but it involved cutting into the trunk so that's out.
5. For the time being, the ultimate goal question is sort of one of those bridges I will cross when I get there. I think the downforce to drag ratio is an ok target.
I am very new to the world of wind tunnel testing and thus am relatively unsure of how the percent of blockage would effect results. Personally I think that as long as all the tests are down under mostly the same variables the numbers should be comparable.
