    2002 Z-28


    I have a 2002 Z-28 A4 with LTs and a lid. I have the 2:73 and will be putting new gears in. My question is would I gain much more with a 3:73 over a 3:42?
    I know a stall is the way to go but I cant do that right now. And is there much more of a gas mileage hit from the 3:42 to 3:73s or very little difference?
    Thanks in advance.

    prolly wont be a gas mileage difference from 3.42 to 3.73. i know that for us m6 dudes that 3.73 isnt different than 4.10 in gas mileage. get the 3.73 you wont be disappointed. sorry for spelling if i messed up, i pretty drunk right now
