    3.73 gears worth it???

    I already have the 3.42 performance axle in my car. It's an automatic and is my daily driver, and i do take it to the track sometimes. Would it be worth it for me to go with 3.73 gears and will i notice a difference? If so where will I feel the most difference? Thanks for the help.

    I agree, go with the 4.10 gear if anything I doubt you'll see the difference you want by going with the 3.73. Besides, if you're going through the trouble of doing the work or paying for it, make it worth it. Just remember you're losing top end the higher the gear ratio.
