M50 modded cars, I need a gearing suggestion.

[M-technik-3]

My car is done 94 M50 single vanos with e36 tranny and now is geared way to low. Great for street and around town but is miserable for Highway. I was thinking about a 3.2ish lsd for it. But I would like some suggestions.

I have presently a 3.73 lsd in the car and it's way to low on highway.

My 3.73 will be for sale after I have a replacement. $150 for it and shipping.

3.25 or a 3.46 would probably be your best bet. All the E36 M3 guys use a 3.46 as their trick diff. It's like a 4.10 for E30's.

I'm running a 3.25 LSD and the gearing is very similar to the original drivetrain (m20b25) with the 3.73 LSD. If you do a fair amount of highway driving the 3.46 is going to bother you after awhile.

I PM'd you about the early euro bumper trim....

That's what I figured. A 3.46 for the US will be a little to much so, is there an in between gear? Say a ration out of the e46 maybe, like the new 330i SP has?

Some E36 guys use a 3.38, but I'm not sure what car those came in. Perhaps Auto E36 M3's? Best of luck,
