shatner saves said:I was wondering the same thing. They are probably little spoilers to deflect debris away from the fuel tank.
Roots66 said:Don't think it's got anything to do with aerodynamics. Too small to make any real difference and it's not like the undercarriage is aerodynamic to begin with.
Jugg2Driver said:My guess is they are their to deflect the air under the fuel tank. It's possible that before those were installed air got between the tank the protective plastic cover and caused some buffetting!
If you notice they are about the same width as the portion of the fuel tanks that would be exposed to the airflow!
Good catch, it does look like the rails extend all the way back. I wouldn't be surprised -- Ford has said this chassis has much more torsional rigidity than before.Svtpilot said:By the way, is it my imagination or do the front subframe frame rails extend the entire length of the floor boards?
