Found a 3.45 rear end nearby for relatively cheap, which would work out to a 7.5% higher gearing. It doesn't give me the tire size options of a 3.08 or 3.27 but should offer some improvement. I think it will take a couple aero mods to get the most out of the gearing change, possibly aerocap or partial front bally pan.

Any estimates of what I could expect for efficiency improvement at highway speeds?
