very interesting numbers, i'm surprised at the effect of tire deflectors, because if the numbers are right than that would mean small plastic rectangles in front of the tires have as big an effect as smoothing out the entire underside of the car? no wonder just about every new car has them.

how well would these numbers transelate to other cars i wonder..., because assuming these mods would have a similar effect on my car i might have gone from a stock 0.29 to 0.263 and i might go to 0.256 when my actuated grill block is done... i very much want to believe this is true, and the way the car coasts certainly makes it possible to imagine.
