      AHAH!! I been looking for this article for days. Here's some quantitative wind tunnel tested #'s for aero tricks on our cars. The lower the Cd the better. Their early 2nd gen camaro got .49 with no spoiler, and managed .29 after all their mods (including a spoiler, apparently they don't ALWAYS increase drag). Here's some interesting numbers off wiki, C6's are around .28-.30, the Prius around .26, a 69 Charger Daytona and surprisingly the 84 transam with the right factory options is around .29 .

      And the rest of the article.

      Wow that article taught me something. I need to find a way to close up the gap between my hood and windshield.
