I replaced the open 3.46 with a limited slip 3.64 this spring. It seems to be great. First gear is useable around town.
I think Robin has a 3.91 in his 535 5 speed. The previous owner converted it to a 5 speed leaving the differential.

I've got the 3.91 in my blk/tan 1990 535iM, it was converted from an automatic like Martin said.
Did you see the post from Jeff N asking about diff ratios? Some good input from the board on what it's like.
If you look at the chart, 1st w/3.46 is pretty close to 2nd w/3.91.
The top line of each gear is 3.46, bottom is 3.91
EDIT: I made a mistake in the calculation... let me get it right and I'll repost.

Based on Jeff's formula im looking at 3400 rpm... is that accurate?
Now why didn't i think of that? thanks

I personally liked 3rd with the 3.46 better because you could pass on the freeway at the high end of 3rd. Now I usually take people in 4th, and the car's not yet in the max power place at the beginning of the pass. However, I really like 2nd w/3.91 around town because you can pull real hard through 2nd yet not really be speeding at the end.Originally Posted by Jason
