same formulas, brick? care

same formulas, brick? care to share?

fyi, for anyone not following the mirrors thread, i just wanted to post some links that basjoos added today. i had a quick look, and these PDFs look like they have some solid, practical aero info we can all benefit from:

The following article also has a lot of basic information about drag reduction in cars.

.
as for the web page calculator, i haven't finished tweaking. i'll try to get it a bit more polished soon.

The Mistubishi Evo IX uses "Vortex Generators" to help with this sort of airflow to maximize spoiler usage. It could also help with square-backed vehicles:

the cool thing about this design is that it will also help keep people off the beach if you want it all to yourself.

I seen these! Think they would help my square backed car?? Would the airtab have the same effect?

From what I know about aerodynamics (and what I saw on "Mythbusters"), the vortex generators could create a "pillow of air" between your back glass and trunk lip. This way, the air could potentially ride over the vortex creating less drag -- in theory.
