Thank you for the information "Old Tele Man".

For the rest of the community that might read this, remember that the EFPD is not how much flat plate area your car physically has. It is the amount of drag that a theoretical flat plate would have of a particular size. It's a theoretical number, not a physical one. But it does allow modders to compare aerodynamics of a vehicle. A modified Hummer might have the same Cd as a Civic but the physical sizes are different. If you use the EFPD, the numbers will reflect the amount of drag on the vehicle, not the Cd.

Thanks,
Ryan
