Well wut size gears do you have? Im not sure what to get..im gonna be drivin to school evryday, so i am gonna have some highway miles..but whatever mod I buy has to perform and really give my stang a boost cuz i aint got enuff money to buy this and that. Im jus scared 3.73's wont be that much of a difference...

 

not much performance wise really, i went full throttle at about 3500 rpms and she gave me a little kick, i looked over at my girlfriend and was like holy **** that was 3rd gear. im not sayin there couldnt have been some water there (didnt see any) but it was kinda cool.

i would suggest 4.10s there really not that bad.

 

Hey dude, I see dat you have 4.10's...what about gas mileage?? Is it horrible or what..

 

Dude, honestly, you bought a mustang. A v8 mustang is not exactly on the top 10 list for best fuel economy. If that's what your looking for, civics are everywhere. Don't get me wrong, I'm not trying to sound like an a$$, I'm just stating my opinion.

And yes it will mess with 5th gear, but in a good way. After 4.10's, my car actually pulled a little in 5th
