I would have to agree w/ Mike... I got the 3.73 and while I am not unhappy I can see that 4.30's will pull better & start better in city driving - On Highway there would be a fairly insignificant RPM change with the Six speed and therefore not a huge MPG diff ( my opinion)...

Of course if you go out & put a little larger tire on right away then you would lower (numerically) your gears..
