For those who intend to get these gears in the future. I would suggest using regular diff fluid for the break in period. Synthetic doesn't allow the gears to heat up enough to work harden properly.

Xviper,

Is replacement of the inner bearing and race essential? I have the 4.44 gear set on the way from my contact in Japan and I want to be sure about the parts I'll need, but I don't want to waste $.

I'm reading several opinions regarding how this mod would reflect in a 1/4-mile. Let's assume for a second that an owner might be considering this mod for a reduction in their 1320 time. Given just how close a 1/4-mile race would be (in theory as shown on page 1) is it really possible to "feel" a .1 difference between a stock S2000 and one with 4.44 gears? I once considered this mod but after looking at the price/performance I came to the conclusion that its benefit is geared mainly for short sprints (say, 5-60 mph) and not necessarilly for high end applications. For an investment of $1500, you could essentially duplicate the 4.44 benefits with lighter tire/wheels or one-up it considerably with a computerized Venom 2000 nitrous kit and have an incredibly "safe" and well-monitored 50hp on tap. I'm not knocking the gear mod for the right application (afterall, I strongly considered it myself) but all things considered, I don't think this is a mod "geared" for the 1/4-mile folks, rather those who spend a lot of time in city traffic, etc. One tenth of a second in the 1/4-mile is equivilent to about 4.8hp.
Spending $1300 (labor, etc) for 4.8hp

Russ, if you read xvipers post about his driving impressions, I don't think 0-60 or 1/4 mile times were his primary motivation, nor are they mine. Xviper has experienced many benefits of the kind that also appeal to me. I would classify these as improved driveability at the low end and moving the sensory thrills of this car up a considerable notch.

Here's a link to that thread:

I too am considering this mod, but mainly for the ease of launching. Seems like dumping at 4k would be easier on the car than dumping at 6k. I also hope that my future turbo on the S2000 will like this mod.

Russ, I don't drag race (anymore) so I'm not going to be spouting off about that subject. However, I must have missed that post about the 1/10 second in the 1/4 better thing. There are many ways to achieve certain "performance" goals. This is only one of them. My opinion has always been that it is the most "safe" one. When you speak of a nitrous kit and "incredibly safe" in the same sentence, I think many will dispute that. You can monitor it all you like but at high rpm, you won't see it when something goes wrong and perhaps that's when it will be too late. Solenoids can malfunction, flow through the lines can be affected, bottles can run low.
"Gears" have always been the "mainstay" mod for 1/4 mile hotrodders of yesterday. Nothing has changed in that regard today. It's a simply matter of physics.
But beyond drag racing, there is the matter of "driveability" under more average "day to day" conditions. But then, I didn't post this to do a "sell job" on it, just to present and document my experience. We constantly hear of burnt out clutches, busted CV joints, broken rear diffs. This mod, IMO, may make the difference to some owners of how sooner or later (if ever) before one of those "malfunctions" happen.
The bottom line is, you do what you do based on what viable information you have acquired and if you don't see the value of a gear swap, by all means, don't do it.
