So I have this S15 helical diff and I didn't think it was supposed to come with the ring gear, but it did. Does this have the same number for teeth as my stock ring gear? I think I remember seeing somewhere that the S15 final drive ratio was 3.692 :1 as opposed to the stock 240 fd of 4.08. Can anyone confirm this?

Sweet, thanks D. I think I have a turbo model since it was off of a Spec R. But I'll just count the teeth when I drop the rear end and pull the wide open to make sure.
