What other cars use this transmission (or one very similar)? It's an Aisin, right? I'm not really sure, though.

Yes! It just seems like such a no-brainer. Sixth is hardly any taller than fifth as it is. It's almost like we have a 5 1/2 speed. And when you need to pass, you have to drop down to third or (ugh) fourth.

Maybe someone could come up with a rear end / transmission gearset. And while we're swapping out gears, let's go ahead and strengthen things up a bit...

I think Ito said he had talked to them. I wouldn't be optimistic except our transmission will be (already is?) shared with the higher-volume Miatas, so maybe they will decide to come up with something.

 

Just a quick note...the Miata isn't a higher volume car. There are more of them on the road, of course, but the RX-8 outsells the Miata by a pretty big margin.

I have pondered the idea of using a rear ratio along the lines of 3.9-4.0:1 instead of the factory 4.44 we now have. My initial concern was to help the tires hook a litle better, or at least spin faster during the holeshot and, hopefully, help the 60' times. Going to a taller tire is also in consideration but I have all winter to think about it.

Aisin is actually a division of Toyota, if my info is correct, and I am wondering which other transmissions may bolt up to the Renesis.

anyone have a website for the FEED 4.77 final drive? the www.pac-gate.co.jp doesnt work.

Thanks,

Try Mazsport. They have gear sets available, maybe even the Feed set. BTW, I have a set of Goodrich KDW's in the 255/45-18 size, which is an inch taller than stock, and there was no difference in acceleration times over the stock size or the 245/40-18 Nitto Extreme 555's that I use.
