RE: TECH: Gears? The Know-All to 96-04 Gear Questions
I've been reading some of the previous posts and a lot of guys are saying the 4:10s are amazing but some are saying the 3:73s are enough for the 96-98's. What should I put in my 96? 3:73 or 4:10?

shucks man, i love my 3:73's it scares me silly sometimes when i hit second in my automatic and it breaks free and kicks sideways. i am an "on the road" salesman and i cruise the highway alot. the 3:73's are perfect, not to little and not too much. i got the 3:73's also in anticipation of the procharger that is going on this week and my local shop said it was a good thing i did go with 3:73's since i am gonna supercharge it. regardless and even without the charger my gears rock! I do think its best that a pro install them though cause they say that if the tolerances are not just right you will burn up the rear end. it is a tricky sort of thing. heres the info i gathered this week. hope it helps and blessings!

stock 3:27's with overdrive:
70mph = 2,250rpm
75 = 2,500
80 = 2,650
_________________________________
stock 3:27's with overdrive off:
70mph = 3,250rpm
75 = 3,550
80 = 3,750

Now the 3:73's with overdrive:
70mph = 2,600rpm
75 = 2,750
80 = 3,000

3:73's overdrive off:
70mph = 3,750
75 = 4,000
80 = 4,250

Type in your tire size, pick your tranny, and the gear ratio, and it will tell you MPH and RPMs
I was very unhappy with the 4.10's in my 03 GT 5-speed...I should have went 4.30's (and half my 30min ride every morning to work is on the highway at 70mph)

Pre-99 Automatic GT's can use a Speedcal from Abbott or Dallas Mustang, 99+ GT's need to purchase a tuner to adjust the speedo.
Due to different transmission gearing, it is best for 96-98 Manual GT's to have 3.73 gears & Auto's to have 4.10 gears.
For 99+ Auto GT's 4.10 gears are the best bang for your buck, for 99+ Manual GT's your best gear selection will be 4.10's at a minimum, as the gear ratio was slightly altered for slightly better gas mileage.
I have 4.30 gears. At the track, with my mods, I was near redline in 4th gear, which is good. With some taller, stickier tires I will make maximum use of my gears.
Hope this helps some more.

However, the real truth is that there is NOT that much difference between the 2 gear sets. If two identical cars other than the gears race (3.73 vs 4.10s) it is still gonna be a drivers race. And if you are not running a pretty sticky tire, espcially on a non prepared surface like a everyday road, your gonna have an easyer time launching with 3.73s vs 4.10s. Hell, I have traction problems as it is now. I don't want a steeper first/second gear.
