Over a periods of months, Phil Knox (aerohead) posted:

• A series of brief Aerodynamics/Aero-mod Seminars
• A series of Lists of Cd change for various mods.

Unfortunately, the thread titles weren't a 100% consistent, so it's not 100% convenient to track them all down.
Here are links to the ones I've found. (If you have links to other's please let me know.)
