Frank,
I'm no expert and I agree with you about angle not being "critical" but I do have a question about the windshield transition. We are really talking about many small changes that add together to reduce overall Cd so while not "critical" a little here and little there still helps. Would it just be better to put a fairing in front of that transition angle to start air upward a little sooner?
There is usually a set of wipers there and many recommend removal (I won't do that) or a fairing. If you put a fairing in front of the blades would it be "better" to angle the fairing from the hood at angle halfway between the existing transition angle or from under the hood at a sharper angle.
Cycleguy,
As for changing the angle of the entire vehicle, I would say that we ALL need to see the vehicle before we can decide. ie: my truck sits higher in the back by 4 inches than the front and the overall underside of the body is already 3degrees higher in back. Dropping the back (changing entire angle) may make sense for my truck BUT after I put full belly pan on bottom, it might NOT make sense. I will have to see what the rear angle underneath looks like when done.
I would say no to the bigger wheels in front as you would likely get much better results from other things first and likely also to make overall combined Cd worse if you already did some mods and then put bigger tires on.
