What diff ratios did the 328 come with?

[old skool]

I know my 97 manual came with a 2.97 open.
I am pretty sure the autos were 3.15.

Were there any other diff ratios for the E36 328?

2.93

you are wrong, all 328 manulas came with 2.93. All auto 328s came in 3.91.

search newbie ;) :stickoutt

2.93 for 5-speed 328
3.91 for auto 328

2.93 for 5-speed 328
3.91 for auto 328

Is the 5-speed 325 the same?

[beatniks325]

no

325 5-speed is 3.15, auto is the same 3.91

Now I need to find out what the autox class rules are concerning diff ratios....I wonder if I can use the 3.15 from the 325...

^you'll have to ask the track guys for sure, but I don't think you can remain in the stock class at auto-x with the diff swap.

Not stock. STX.
