dang, i went on youtube and researched both. When i look at 3:73s i can't tell the diffrence between those and stock, when i look at 4:10s it looks like a totally diffrent animal. I've been thinking about my choice for a long long time but now i'm def. leaning towards the 4:10s for sure. The 3:73s don't even look any diffrent than stock, on youtube video anyway

Heck if your scared of 4.10's go 3.90

What is gas mileage? Is this a mustang forum or a civic forum?

Don't fear the gear. 4.10, 4.30, or 4.56 are the only gears that should be put in a mustang no matter if your NA or FI unless the car is used for road racing then use 3.55 or 3.73.

haha 4.10's or bust go to cliffyk's page and find the gear calculator if you wanna know the speeds...

4:10's will really wake up the car, did it and never looked back. here is a cool calculator to figure out your speeds with the gears

Man that's a cool graph. I just wish I didn't have to redo the gears. The 3.73's are a good gear but when I rode in my buddys 01 gt with a few mods his car felt fast as hell (but not fast as mine, lol)...
