Pete,
The coefficient of drag value for the 996 GT3 is 0.30. I believe the 997 series is a hair lower.

Careful what you use them for, they do not tell the whole picture.

Cd is a bit pointless as its not comparable across cars. You need CdA which is drag times area. Then you get what a cars actual drag is.
No idea why manufactures quote Cd????
