If anyone has measured the CdA of their cars before and after aeromods, I'd love to see your results.
I measured the Cd of my modified 2003 Beetle some years back. (By coast-down) I have my calculations around here somewhere, but no clue where to find them. Result: Cd = 0.31 with the modification. I didn't measure before, but the published number is 0.38.
