I have a pretty big question here. I am not making any accusations, but just asking a question.

How does this PolyDyn coating help protect the gear against failure? A PolyDyn coating is for reduced friction only. This lubricant can be bought by the bottle I'm sure for less than $100 right? Can you just soak your ring & pinion in this stuff? I'm sure there may be more to it than that, but that's why I'm asking. What's the difference between this stuff and any other gimick item sold like Slick 50 or that other stuff that had an info-mercial? It has been proven that treatments such as Slick 50 have very little to no effect on metal wear and fatigue.

Also, the polydyn site says this:

you're going by his word on the polydyn stuff.

 

i was thinking it would be just like teflon in a pan........which doesn't make it stronger but would reduce the friction and temps....???

 

can you please clarify this?

I thought that no one has installed the KIA 4.77 gears in their S2000s yet? And from your previous posts you said that of all the 4.77 gears you've sold there was a 15% failure rate. Does this mean that you've sold the KIA gears all along?

 

They aren't "Kia" gears. They are "Mazda" gears.

These gears that are used by Kia, Honda, and Mazda, are all Mazda designed gears. I have no idea who the manufacturer is, but it is Mazda's design.

Please ready through the thread entitled "The truth about the Honda S2000 Ring & Pinion". It will give you all the answers you need. Here is the link:

If that doesn't help, then read the thread entitled "Rear gear-What mazda is our rear gear the same as??????" Here is the link:

Yes, these threads are long, but you can just skim, then slow down when you see something you think is important. There is TONS of very usefull information and also many other links to lots of other usefull information.

I'm not trying to be an a$$, but please just read these threads before asking the same question that has been asked several times.

Honda, Kia, and Mazda utilize the same ring & pinion in the differentials of some of their cars.

 

i've read all those threads already and since you started all this, i'm sure you wouldn't mind it if you would reclarify stuff.

and the only reason I refer to them as "KIA" gears is because of the fact that they can be had from your local neighborhood KIA dealer.

 

I traded my Z for a used S2k and I notice a huge lack of bottom end pwr in the trade off. I've read many threads resulting this change and how it's great it is to simulate the feeling of more tq down low. My question is there an extra shift between the 4.57 as opposed to 4.77 ratios in a 1/4mi stand point? I'm not a drag racer, but i do like to play in the streets when the opportunity comes. I would like a that piece of mind knowning it will give me an advantage instead of making me slower with an extra shift. I know its been said many times the s is not a drag car, reinforcing the diff help it?

 

scott, a search on the coatings will reveal some analysis by road rage.

 

Ok.. so here's a short version

I like what Rick has done here..

Lets be more clear on the $300 offer

Basically... the only way you MIGHT be able to return this thing is that you NEVER install it or scratch it or anything.. you install it, and it breaks tomorrow... tough luck.. that item is sold "AS IS"

Now granted the chances of them breaking are RARE.. so its not something that you should be crying about.. the 4.77 failures could have certain variables that are not regularly found in your average sports car... FOR EXAMPLE: I dont drop the clutch like the guy with the ITBS... something like THAT might cause you to get some oil spills on the road.. So if you do THAT, then dont pay $300 for this unless you have an abundant source of differentials...

To the person that mentioned something about Summitt racing and cheap Richmond gears... ummm... Buttstangs are a dime a dozen out there... so that product sells in MUCH larger quantities than this 4.57 gear.. so economic variables will tell you that not only will they cost more to produce (maybe not THAT much more but still), but since the average S2000 owner is WILLING to pay $590 for them, there is no reason to sell them any cheaper.

This is like an exhaust system on a 911 twin turbo... do you REALLY think that it costs anything close to 2500+ to PRODUCE an exhaust for that car... HELL NO!! BUT, the fact that the very selected few that want one are WILLING to pay for that... then walla! thats the set price. Comptech SCs dont cost anything near 4500, but thats the selling price... because that is the premium of exclusivety and speed.

100 bucks to squirt some Polydyn dry film lubricant on there?
