Kevin, u might have a good point since Clay is getting better mpg tham I am even w/bigger tires...But there is more wind resistance created by air flow through the grill than windshield. I think the increased drag on a lowered front may be produced by greater downward pressure over the body of the vehicle and consequently greater tire friction/vehicle weight. Which also accounts for it riding somewhat better than a hay wagon now.
