overdrive gears

[alscrimp]

Anyone know where you can purchase overdrive gears for the 5 speed aveo? I'm looking for a 0.50 or 0.60 ratio. I would like to replace the stock 0.76 ratio for better mileage.

If I recall correctly, the tallest overdrive gears are found in the newer aveo's. And the gears are 0.71:1.

i dont think the car would make it uphill with a .50 fifth. i cant off the top of my head think of a car with that high of a ratio without some sort of "close" final
