Hey, i was lookin to move my '04 GT from a 5spd to a 6spd with a higher gear ratio. Give me a little more pull out of the lower gears but wont completely blow my gas mileage on the freeway (i put about 80mi/day on the car). Anyone got ideas? Should i just take the setup from the cobra,i know they got a higher gear ratio that the others or should i step up to 3.73's or something?
