what are the Final Drive Ratios of all e30's ?

I need a new diff for my 84 318i and i want to know what are some of the final drive ratios for various e30's? i will get whatever is lest expensive from ebay that will fit and work with my car, althought i don't really want one thats a little too high of a ratio for my car. somethine like a 3.9 or a 4.1 would be good.


thanks

Scroll down to the diff gearing section.

My old 1985 318i automatic had a 4:10 rear, my 1989 325i has a 3:73 diff. Don't even think about a diff from an "e" model, it is far to low (numerically).

Thanks for all the info, but when it comes to getting this car running, i don't think beggars can be choosers. but yeah, anything numerically lower than the 3:9 that is in my car wouldn't be too satisfying.
