On the wiki I was going to see if I could add more info on my car but the formula "Frontal Area formula = Height * Width * .84" seems to be a bit off for the spread sheet.

The only I can get any on the cars entered to work was to use Frontal Area formula = ((Height * Width * .84)/12)/12

That just does not seem right to me I understanding dividing by 12 once to go from inches to feet but I do not see why it has to be done twice.

I just added the Frontal Area for my Grand Prix as ((54.7*72.7*.84)/12)/12=23.197ft^2
