really just depends on what your looking for out of your car. I dont care about the mileage so I went with 4:10 gears. still getting 19 mpg around town

No less than 4.10s, you will not be sorry.

I am going to go the opposite way, I say no more then 3.73's. Unless you are wanting quicker time at the track and going to have some good tires/suspension.

if I would of went 3:73 instead of 4:10 I would have been kicking myself in the a$$. 4:10 are really not as drastic as you would think. if your driving 75 on the highway everyday then you might not want them. but for the most part I think they are a good all purpose gear. just my two cents

I know I would hate my car with 4.10's because I don't like it a lot of times with 3.73's.

I dont understand 3:73's are not much of a change from stock. around town I dont know how you would tell the differance from stock ?

I dont want to be shifting more then I am now. First is almost pointless already "I mean how quick I have to shift not spinning" 2nd is not much better, I like 3rd and 4th, but I feel I wouldn't even like 3rd with 4.10's. Everyone likes the low gear becuase it makes first and second pull harder, but you are shifting at lower speeds, the only reason I would ever go with a lower gear is if my car would pull itself good off the line with slicks or if my car wasn't getting near redline at the track in my last gear change.

welcome to the site...my opinion 373s are a perfect gear if your planning on "modding" your car in the future and trust me you will see a differance from stock

Yeah you will see a differance but from 3:27 to 3:73 seems like a waste of time and money just my opinion. it really depends on what he is looking for and what his future plans are with the car. another thing to consider is what tire size you plan on running. that will affect your gearing as well

I love my 3.73's but then again I started from a 2.73! 3.73 is a good all around gear, good power low and won't kill you on the highway!
