I talked to Elton from Raceline and he stared me away from 4.57 and said that 4.44 is much more reliable and a better fit.

Where can I buy one?

there is a guy in the for sale form selling his rear diff with 4.44 gears

GB section Motorklass, but they are on backorder right now.

I was told that Motorklasse is not as high quality as the original Mazda part.

Elton suggests Mazda 4.44 and I think its only like $400.

Where did you hear this and how are they inferior? According to Motorklasse, their 4.44 gears are manufactured by Mazda. I got tired of trying to source them through a Mazda dealer, so I've been waiting on MK's 4.44 gears. And this is the first I've heard of them not being up to OEM standards.

No idea who said the 57s are not the quality of the 44s. I think they are both top quality. To say one is inferior is pretty much stupid.

The fit? I've never heard of the 57s not fitting

I've actually seen more threads of the 44 / 77s breaking then the 57s but of course I'm sure I missed some.

4.44 is a waste IMO, you won't notice a difference. I you want to feel like you have upgraded your diff then go with the 4.57's or better yet 4.77's.

Have you seen the gear graph ratios on an AP2?

The 4.44s are very close to the 4.57s.

Not to mention they are a bit better for HWY driving.

The 4.44s on an AP2 are a bit "faster" than the 4.57's on the AP1, or at least that's the way I see it on paper.

Just realized he had an AP2, my bad. I know the gear ratios are different from that of an AP1, I still think I would atleast go 4.57's if he wants a noticeable difference, then again not sure what his purpose is for the gears, maybe the 4.44's will do for him?

Goodluck either way.
