The cd factor is not so important, but rather the air drag index factor, which is the drag coefficient x Frontal Area of the car (cd x A). The lower the number the more aerodynamic the car is.
Also many nose-heavy cars use lift in the front to become more balanced at high speeds.

Bryan-
If you find the pic of the MK1 MR2, please post it up!
This isn't the one I was thinking of, but it might even be better.

Also check out the MR2OC thread linked in the above page.
And while I was looking around I saw some very interesting things. :)

Allllrighty then, I like the ABS intake, let's do something similar.
