wtf?? lol

from a dead stop.....which gears do u think would most likely win in a drag race.......

hypothetically speaking.....if everything else was completely the same.....tire spin....perfect shifts...everything


which gears do u think would be the fast from a 0-90 mph run

I drive at 90 sometimes and do care about maximum acceleration from 0-60 and quarter mile so yeah there is for me, they don't accelerate your car as fast as the lower ratios such as the 4.30's - 4.44's. They do provide you with accelerating your engine faster though and giving you more bottom end respons on intial throttle aplication. People get so confused it seems and can't make this distuishment.

Get them with the understanding that they are for fun and limited small track aplications, but realize that they arent nescisarely going to propell your car the fastest in a strait line. The s2000 handles awesome, It needs a little more balance in the strait line performamce so I have modded mine accordingly with this in mind along with bolt on's.

I should also mention that as your power goes up the more the higher gear ratio's are a draw back for maximum acceleration. Stock for stock the difforence in gearing is smaller but still apperent. Have fun with the 4.77's but understand the distiushment between your bennifit of added tq multiplication and all out acceleration of the lower gears. Realize that in a drag race your rpms never dip below Vtec so top end performace is where your at. As soon as you shift out of first gear your at a disatvantage with the 4.77's. With this in mind, You only need enough gear reduction to get your rpms to fall withen an optimum range of the s2000 power band. To much multiplication and you will lose car acceleration but be able to pull a trailer. Not enough and your cars power band will be streached to thin and your engine will bog. 4.44's are right at the sweat spot baby! Ok get it?

I recommend to anyone to try my tire mod sice it is free, assuming you need a replacement, before investing in the wrong gear set. Do some dragging with them and get an understanding how your car responds to the changes before jumping right into an extreme. I understand the idea of getting the most for your money but more gear isn't always the better choice so take some time to do your own resurch and play around with the diforent sets if you can so you will have first hand experiance before your investment. thats all I can say about it. Good luck!
s2000junky, Can i ask you what rear tire size to mimic the 4.3 gear ? very easy to do and get the same benefits as the gear change. i will try it this weekend.

Sure i can help you with this, you have two choices. One of them is at the sacrifice of a slightly narrower width tire because this is what is available on the market. I currently run the Azenis 615 215/45/16 w/factory wheels. for a gear ratio of 4.33. This tire has a stickier tread then the factory s02's so it overcomes any traction loss do to the 1/2 narrower tread. It also make for a lighter package with less rolling resistance so it has multiple bennifits of increasing your acceleration over just a gear change alone.

If you want to stick to a closer width but still get some gearing atvatage you can go with the 225/45/16 for a ratio of 4.26. Hankook rs2 makes these and are sticky like the Azenis but not as stiff in the side wall. You will be reducing your side wall profile so this will also over come this flex over the stock s02's. The Azenis are stiffer then both the Hankook and Potenza so2's. There could be another brand or two floating around that would fit these sizes but I have spent alot of time resurching this and have found the Azenis and hakooks to be the best choice for cost and performance. I don't think you will find a better choice out there for my tire mod.

It should also be noted that the performance of 4.77 gears would be different between an ap1 and a ap2.

From what I understand the 4.77's are better suited for an ap1. The ap2 has shorter gears to begin with so the 4.77's are an overkill.

I might be wrong but I thought it should be mentioned.

You are right about this... the Ap2 has an effective gear ratio of 4.20 -- 4.22ish plus throw in the added penalty of 1000 less rpms and you arn't going to cover any ground very quickly.

Playing with rear tire sizes would work perfectly for an Ap2, however I have not resurched available smaller sizes that adapt to a 17 wheel. There may not be any but its worth you Ap2 owners to do a little resurch on this and find out.

i wouldn't agree with this. i have a traffic-filled morning commute and i found that starting in 2nd works fine. with the 4.77 starting in 2nd feels ALMOST like starting in 1st with the 4.1, and you have more pulling power than you'd need in traffic.
i agree ^^ 4.77 makes it much easier to drive in traffic.
2nd works fine @ anything over 5mph - feels almost like first gear stock.

What rpms are you turning while going 70 mph with the 4.77's?

I'm planning to just throw on a pair of 16in. wheels from a FF car to test. I assume the tire height comes into play to mimic the gears, correct ? Can anyone link the page to the gear calculator ??

i'm estimating about 4600-4900 rpm. i was trying to gauge it today but it's kinda hard cause i still haven't installed my yellow box (speedo calibrator)
