So i'm pretty new to mustangs. I've had probe's up until now, which as we all know where supposed to replace the mustang, but def. can't compare. I've got a pretty much stock 03 gt. I'm lookin for some gears, but i want to know some things b4 i make my purchase. First, wtf is the stock gear. Second, how big of a gear can I get without having to change the carrier. I'm on limited cash hear and am really gettin sick of a certian SS TB at my work thinkin he's hot sh*t, cuz I can already take him on the highway, just not from the stop. I was thinkin 4.10's or even 3.90's. Def. gonna go with motive gears from AM.com Any help would be appreciated. Thanks.

 

Do you have a manual? i love my 4.10 gears but if you plan on going F/I you might want to consider 3.73s. I think there is a sticky about gearing and will give you a lot of information. If you do much highway racing i recommend 3.73s you get more speed out of 4th gear.

 

stock gearing is 3.27

what is a SS TB?? an SS camaro? if its an LS1, there is no way u beat him from a roll with your mods. but if he is an LT1, than its possible if he was an auto or something.

if you an auto - go 4.10

manual - 3.73,3.90,4.10,4.30

all depends on how much highway you drive. I'd say that most people go 4.10.

but if you drive a lot of highway, go 3.73. yet some people who drive a lot of highway go 4.10 and 4.30. they dont mind listening to their exhaust for long trips at 2600+ rpm's

at 70mph, 3.73 put you at 2250rpm i believe
4.10's at 70 put you at 2600??

those numbers are close enough

if your auto you will need a tuner to correct your speedometer
if your a manual, you can buy a speedcal for like $100

id just buy a used tuner either way. that'll run you around 2-300 bucks

and no, you do not need another carrier with stock gears

 

and for future references, use the search feature on our forums. i was bored so thats why i typed this all

with 3.27 at 70mph ur at 2000rpms
