OK... that's an area I could help with, if I could get access to the config files (or if I can work with someone that has access).
FYI... Coast down testing thread:

Also... looked at the link "about cars, aero, cd and stuff" and realized that's not what I meant... I recall we had some threads on how to determine frontal area (useful if there is no info from the manufacturer, or if the area has been changed by removal of mirrors or addition of front skirts), as well as threads discussing methods for determining Crr, which is needed in order to more accurately calculate the CdA. Of course, there's also good stuff that could be referenced from elsewhere (non-ecomodder content, if you can believe it
). Having an area to capture all the different "how to measure" stuff (and then a place for users to post the results) is what I was thinking.
