IMHO, this is a WOFTAM that would make three-fifth's of five-eights of f4rk-all difference.

If you want down-force, you must create negative pressure under the car, and permitting more air into the space behind the bumper is not going to facilitate negative pressure under the car - more likely to add to the pressure.

I asked an IRC buddy who is majoring in Aerospace Engineering and he thinks that it won't make much difference (but he's still a student, so take it with a grain of salt). He also gave me this link to a de-classified document about NACA ducts from 1945.

Nice. 1945 ? Surprised this was not covered in 9th grade Science class
