There are no flat surfaces on Freds car, nor Vesco's, Teagues , Whites and the
is a reason. Air flows smother over a curved surface. Air trying to push up on a
flat sided vehicle creates a hell of a turbulance and causes lift on the flat
top surface. We have seen a lot of this.
Hoping for a grea t speed week and world of speed.
