just a video of my truck at opening day at local track fig a few you guys like seeing how the truck does on the spray.
Not saying this is the reason he said it but technically it would improve aerodynamics by reducing the drag. You would actually decrease frontal surface area by lowering the truck since the tire face no longer acts as frontal area in the wind. Tries actually cause a fair amount of drag because they must be exposed in some way, look on a lot of late model cars you'll see little lowered portions deep under the bumper just in-front of the tires to deflect air. Theoretically decreasing the drag does equate to a higher speed capability.how do you figure lower means faster?
