I drove it with 3:55 gears from vista to Fontana to run it at the strip. Could not pass tech, no roll bar...Drove it back. Just over a tank of gas, 76 miles one way. Now it has 3:23 gears.
Well, the 3.23 gears will make it a lot easier to drive on a highway trip for sure. Maybe you just need to make a long highway run with the new gears and figure out what the mpgs are to help decide.
