Small Vs Med diff case Q's

[liv2race]

hey everyone,

Ok, I have been doing my homework on my new bmw. I know about the med case and small case. however, Im not 100% sure about the apps.

I know all 325's and M3's have the med but the 318 seems to be mixed. Some same all small case and some say it could differ. after a search here and google no def answer.

Basicly Im looking for a new rear for my car. I have seen a few (3.91LSD) from 318s but not listed if small or med.

Thanks!

All 318's came with small cases from what I've seen so far.

S3.91 is a small case for 318.

^ Second on that, all 318s were small case, all M3s and 325s were medium.

Thanks for the confirmation.

Were 3.91LSD optional in med case?
