What gears should I get?
 

I dont know what gears I should get. My Mustang is a daily driver, and if i get accepted to a certain college i might have to drive an hour away, so i need something that is still decent on the freeway that i can keep in 5 and still be under or at 3 grand.

A good gear for a daily driver, in my opinion, would be 3.73's. Thats what I got in mine, and all I do is drive it daily. They are also good if your going to add a power adder later on. The only thing I can think of that you should do is to get a power chip to off-set your fuel use. The chip can also calibrate the speedometer for what ever gears you put in.

For a daily driver... 3.73s...

Also, 98s don't need a chip or speedcal to correct the speedo, just a 14 dollar speedo gear....

3.73's are for you. You will notice a big difference in performance and you will be way under 3000 rpm (3000 rpm's is about 90 mph in my '00 GT with 3.73's, 70 mph is well south of 2500 also).

Can anyone name off different gear sizes, and what there Pros and Cons are..I'm not sure what gears to get either :D

The 2 most common sizes you will hear talked about here are 3.73 and 4.10. The higher the number, the taller the gear is. The taller the gear is, the faster the engine can climb through the rpm range, but at the same time, it decreases your speed for each of those gears. For instance, with stock gears you can top out 2nd gear at lets say 65mph and hit 60 in about 5.6 secs. With a taller gear, lets say 3.73's, you will top out second gear at 60mph but do it in 5.2 secs. These are just examples. I used them just to give you an idea of what gears do and how the higher the number is of the gear you have affects yor mph and the amount of time it takes to accelerate. Also remember that the taller the gear you use affects your fuel usage. You will always use more fuel with taller gears.
