I have an 05 V6 and I like to drive it rather spirited on the back roads and highways. I'm not a drag racer nor am I pushing out 400 to 500 horsepower to rear wheels, just the stock amount. So my question is; is an upgraded 8.8 rear end really needed for what I'm doing? The 7.5 can be upgraded to 3.55, 3.73, or greater gears. So would an 8.8 benefit someone like me at all?
