With all of the variables in real world driving, I don't think the full rear fairing is practical. If you are headed to Bonneville, then absolutely, you will need it. I still say, start with installing a vacuum gauge and learn how to use your right foot. I believe a few years ago, a guy entered one of these cars in a mileage event and averaged 108 mpg. That was on a closed course, fuel economy event, probably 45 mph top speeds, not the real world. Mirrors, passenger seat, spare tire and any unnecessary weight were removed. I believe he taped all body gaps and rolled window down to get in and out. Oh, he did make his own version of a nose that was quite a bit larger than mine. It reminded me of a cow pusher on the front of an old train.

Aren't the stock tires larger than that? I do plan on installing a vac gauge. I'm pretty good at staying in constant pressure but this should help visualize everything. You are right on the milage but it wasn't closed course. Lol I do remember that article cause I plan on doing something similar
