I know there are mainly the 4.40, 4.57, 4.77 and some intermediate ones, but is anyone planning on going higher such as 5.11 or anything hgher than 4.77? I am curious also if anyone ahs done this yet, because I know J's Racing has the many different gears available curious as to who has started using the gears...I want to buy gears soon but I want to make the right choice I wanna know how aggressive anything after 4.77 would be and some opinions...

4.77s makes your top speed about 138 for the AP1. Anything higher will drop your top speed. I think 4.77s is very aggressive and wouldnt go any higher.

since the Ap2 already acts "like" the Ap1 with 4.44s your best bet is to get the 4.44's which would make your car "act" like the Ap1 with 4.57s...if you want higher go to the 4.57s which would be like 4.77s in the ap1...well u get the picture now.

5.1s are pretty much race only and they are kind of like the point of dimenishing returns...yes they make u faster, but with how much you loose of the top end, many find them not worth it, unless you are never going above 120 and need all the acceleration down low...kinda something a race team would do for a very technical track

I hope you are NOT thinking that "higher" gear ratios will make you quicker or faster because it won't. If you were to get 5.1 gears, your top speed will be limited to about 120 mph. You will need to get into 6th gear to finish the 1/4 mile. Some guy with 4.44s or 4.57s will woop your butt since you will have to shift at least one, maybe even 2 more times to make it through. The accelerative advantage of 5.1s will be more than trounced upon by the time it takes you to shift 2 more times.
Even a drag to 60, you will suffer the disadvantage of having to shift so much.

It's amazing how many people can't seem to understand that gearing only transmits the power -- the engine provides it. Changing the gear ratio does not make you any faster overall.

The only real use for it in a racing situation is to customize the car for a specific track. For instance, at track X you may have a turn where your apex speed is 53 mph. That's lower than optimum for third but too high for second (with stock AP1 gearing). If you change the gear ratio around a bit, you could put it perfectly in the power band for one or the other. But then you have to consider the other corners and make sure you don't mess anything else up.

For straight line acceleration, changing the final drive ratio is not going to buy you anything.

I don't think anybody that posted yet has said that. yet...

Although gears can make you faster.
Stock 0-60 and 4.57 geared 0-60...the 4.57 is faster because both only shift once. Gearing does make a car faster assuming you can shift lightning fast, but it doesn't get you to as high of a top speed

Since I have an ap2 I would only need to get a 4.44 gear instead of the 4.57 to make my car "act" like an ap1 with a 4.57 gear?

This is where you are incorrect. The stock geared AP1 can achieve 60 mph in second gear. The 4.57 geared AP1 will not. 2nd gear will only get you to 58.8 mph. Therefore, you would need to shift one more time with 4.57s. However, I believe that the advantage in acceleration of the 4.57 equipped car will more than make up for the time required to make one more shift, assuming that the operator doesn't eat up that gain with that extra shift. IE, If the driver is a slow shifter, gears won't make any difference. The only difference may be in that a driver of a stock geared car will be slower than his own time in a 4.57 car.

oops...I thought it went to 62 with 4.57's maybe thats the 4.44's I know stock is 67.

Well, this is what I was trying to say: Stock 0-58.8 will be slower that 4.57 0-58.8, etc.

And riceburner...I guess you got my point huh, redundency prevails

uh... yes it does. why do you say changing the final drive ratio doesn't make the car any faster in a straight line? hell, muscle cars have been doing this for YEARS!

not only did my ET go down on average (13.6 so far, but I think a 13.4 will be possible), but my traps also went up. i can whomp on a stock S2000 with my 4.57 geared S2000 from any speed roll or from a stop.

and i'd be more than willing to bet that if you can shift, a 4.57 geared S2000 will do a faster 0-60 than a stock S2000, even with the extra shift.
