from what ive seen compared to a lot of other cars a .29 isnt all that bad, its on the lower side of average ?

but I could imagine just a few things like a 1.5 drop all around, some wheel covers, a lower front dam and maybe some ground effects (not the ricey kind, but a nice, clean aero effects, maybe a boat tail of some form (along with removal of the rear wing)

the biggest problem I could see was the gearing itself, 1st and 2nd are super short, and 3rd is quite tall in comparison. so just to get smooth shifts from 2nd to 3rd you have to take the RPM's higher than Id prefer.
but it wouldnt take much retooling to get it a little more even and make all the gears a little taller.
all in all, I honestly believe with just some minor aero mods alone it could see 40+mpg, and a retooling of the gearing could get it up to 50mpg.
