TBH, I kinda forgot about this thread LOL
I'm back to it though! It seems that my car has hit a "fuel economy ceiling" and will not break it. 48 mpg is as high as my tank average can get, and this is with heavy P&G EOnC.
Is there any aero mods that I can refine? Do tire splats really help?
Side panels will reduce drag, I have just got to figure out a way to attach them to the body! I really want to make a pair for each side, one flush along the outside edge of the car, and the other along the inside of the tires from front to back.
For example, the inner ones would be similar to those found on the Bonneville Corvette you posted, freebeard. The outer ones would be the same as everyone else who has ever done them!
