^ you ve got the 6 mt? rx8?
what about the accelaration with the stock one? on a drag race is gonna de much better than a stock one? max speed? does the 6th gear goes to the red rpm? over than 250 km/h? when you installed the part did you feel the difference?

I don't drag the car (6mt) but it accelerates faster and it is very noticeable on the turns since it now tends to gain speed quicker after the deceleration.
It is the best mod you can do while remaining NA but you really need to find a good tuner since it is a must to perfectly fit\space it with properly built spacers 99% of the times.

^ did you use the feed part? any promblem on the installation?

We needed to space them in order to fit properly,installing a final gear requires precision. Yes, it is a Fujita Engineering\Feed part.
I now have a problem in my differential but it shouldn't be the final gear and nobody else here in italy had problems after the installation and after several kilometers.

you mean on a screw-cutting lathe? there

You need to find the perfect size for the spacers since the ring\pinion needs to run smoothly without too much resistance. That's why i tell you to find somebody able to do that, mounting it without adjustments could work but you risk to put too much stress on the parts during the break-in period, with the chance of making it a break-it period :D

i need to process the pinion too fit it on my car? i would install on Mazda because i know the owners. what did you mean to put much stress on the brak period? i case of the shortest quicktime

You need to adjust the parts "case by case" because every differential is not identical to the others. I needed to process the spacer and the pinion, a friend of mine needed to processt just the spacer, for instance. It differs from case to case.
If you don't have the final gear fit properly you might experience grinding noises or put too much stress to the ring and pinion, risking to grind or break it.
Hope this helps

yes i understand you now Just my english aren't so good. i am gonna take care will installing it and to be svre tha it works and turns soft!!!! with the hand!!! where did you buy the part? and how many euros on your door?

I bought it from japanparts, fast shipping (5days) after the part was built. With the low dollar you will pay around 550€ for the part shipped + customs if i am right. You also have a discount as an rx8club member, just type RX8DISC in the comment box.

Let me know if you need any other kind of help, i will try to help you in any way =)

what about the gasket? i am gonna use the same or i would need a new one?

you will probably (90%)need a new one, especially if you have a lot of km on your car. I could reuse the gasket but i was pretty lucky.
www.onlinemazdaparts.com sells a gasket kit for the installation, it is perfect for this job!

I'd say definitely not. The FEED is kind of an adapted kit in a sense requiring parts that won't exist in production from Mazda.

Anyone know the gear that already exists in the 8

4.44 i believe

confirmed, 4.44:1

any one know where is the best price and good accommodation to order the part?
And come at home quick?

I can provide the new 09 Factory ring and pinions for $675 but it will take up to 6 months to get it.

Paul.

only 675 for the stock one?
but over 6 months?:banghead:
is that certainly to wait for the part?

You've been PM'd.

Paul.

Lets hope the 2009s will start having prangs soon - then we might get the 4.77 cheap cheap

Does anyone know if we can just swap the 2009 gear or the entire differential into an 05? That would be a heck of a lot easier than modifying crap parts from FEED...

would be very surprised if it was anythig more than a straight swap ....

feed does not make crap parts either.
