ok so i am looking into buying a set of gears and i read up using the search function on here and im not sure what im reading....i have a friend that has 3.73's and when me and him raced by the time i was halfway thru 4th he was shifting into 5th...i really dont want to have to shift into 5th seeing how i get no power...so i was looking at a set of 3.55's like an 03/04 cobra has or a mach has....is this a good idea or not?

any help is appreciated...thanks guys

its just that all this gear talk is confusing the hell out of me....and now im not sure which way to go...so yea

i'm confused too man. it seems like there's so many different combinations u can use. there's 3.55, 3.73, 3.83, 3.90, 4.10, 4.30, 4.55... i don't have a clue what the difference between all of em is

Stock I think you have 3.23's. Everyone usually goes with 3.73 or 4.10 gears and there's constant arguments about what is better for daily driving. I heard that 3.55 gears aren't worth the trouble because your ratio isn't being improved too much. I can't decide between 3.73 or 4.10 gears for myselfbut I would at least go with 3.73's.

Dont do less than 3.73s. So make your decision between 3.73s and 4.10s.

Highway=3.73s
City and less highway=4.10s

373's or dont do them at all.

If you want to have fun 4.10-4.56 That might be a little much for a 2v but it would be really fast if you could keep the tires down.

general rule of thumb that is followed is 3.73 for a manual and 4.10 for an auto... seeing as you said that you have to shift go with the 3.73... if you are racing on a track, unless you have ridiculous power, you won't be shifting to 5th in the 1/4

Why don't you drive your friend's car and see how you like 373's? from what I understand, 4.10's will require some tire and suspension upgrades if you want to have any kind of traction.

I have 4.10s and i had to do full suspension and i got 315/17/40 on 10.5 inch rims. Now i can hook up. Before with just stock suspension and 275's, i would have a hell of a time on the street/track. I am glad i got the 4.10s, i had 3.73 and they didn't give me what i wanted, but 4.10s did. I do shift into 5th in the quarter mile but right at the end though about 100ft before the line. 5th gear has a lot more power cuz of the 4.10s. But with just a semi bolt on GT you wouldn't shift into 5th in the quarter mile you would be real close to it but you wouldnt have to.

to the op--- your 5th gear will have more power with steeper gears. I went 4:10s also, still 23mpg hwy. No regrets
