Don,t it seem that many cars and trucks etc are probably geared for higher rpm than need be to compensate for load or 20 degree hills. If need be we could always down shift. Don't hear of anyone complaining of wind resistance when driving the max speed limit I drive my Z around rural areas.in 5th and 6th gears getting the best mileage that is without stop and go traffic. Then on the highway I'm wishing I had a 7th gear to get my revs down. Only solution I see are larger o d tires. I can always go back to stock if that don't help.
