Electrical genius I am not, so all this I am a battery stuff I am trying to learning quickly. But we all know that friction is our MPG‘s biggest enemy. Has anybody on here ever thought of ceramic wheel bearings? These are used all the time and drag cars so that there is no loss of horse power. My friend gets his from a guy in Pittsburgh and he said he put them on his regular car to get better gas mileage. If anybody has the exact size of the bearing please let me know. I have not actually taken mine off yet to see how it’s built but I have been checking with companies already to see if they will make me a set when I get the measurements.
