Hunting Rx8 Differetnial Gears
Doe's anyone know any company that may have a ring and pinion set for the RX8?
Do any Japanese companies have sets available?
The OEM manual gear set is 4.44, looking for something in the 5.0-5.4 range.
Cheers.

If you do a search for "4.44" you will get more threads on the subject

Ditto on a desire for the numerically lower diff.
With a properly tuned turbo, 1st is too low...you lose time with the 1-2 shift. Also, it would be nice to spin at <3500 rpm @ 75 mph.

Why not opt for the slightly more aggressive final drive, and go for a taller 6th gear? Is it very difficult to machine a new 6th gear? It seems like it shouldn't be too difficult, but I haven't seen many people even mention it.

I agree, I would love a taller 6th!
I never NEVER use 5th - I accelerate to 8000 revs, thru third or fourth, then drop into sixth for cruise. You wouldn't be giving up ANYTHING with a higher sixth, there is no acceleration there anyway, you'd probably just gain gas mileage.

in 6th, 20mph is 1k, 40mph is 2k, 60 is 3k, 80 is 4k, etc

Mazmart is planning to sell 4.10 rear ends for the RX-8. No word yet on availability or price. That would be the way to go in my opinion. The rear end is already too high numerically. You already shift through the gears too fast for normal street driving.
When is higher, high enough? Why does everyone always want more? When is it a waste of time to go any higher? Why not a 10.1 rear end for all the acceleration freaks so they can hit max rpm at 100 mph? You'd get there fast! When will it end? Why can't people go down for once assuming they already have too much?

Therm 8, I didn't even think about that. D'oh. Someone build me a taller 6th gear...please?

Unless you floor it everytime you drive it, why do you need more acceleration? You will absolutely get noticably worse gas mileage. It probably won't be much more acceleration anyways. At least not enough to make much of a noticable difference.

I appreciate your concern and your advice is always more than welcome. Thanks RG.

I do agree that a taller 6th gear would be nice. I'd actually like to see 5th and 6th spaced out a little farther from 4th. The car almost needs a 7th gear when cruising.
