    Has anyone looked into running a lower gear ratio in the transmission for racing?

    I remember seeing some sort of experimental differential for sale a few months back. Maybe that would provide the ratio you're looking for. A lower ratio would make the car faster, but not as quick. Is that the goal?

    I'd be up for a re-gearing that would provide less acceleration and more range. :) There seems to be enough torque to go with a longer gear ratio...

    I think that there were some cars that used the same Borg Warner gearbox as the Roadster but with a lower gear ratio. So, it might be possible to buy a different set of gears. Maybe EvWest would know about this?

    Gear change will not help that much for more range, i.e. the gains would be the motor efficiently delta in RPM.
