Hey all!
1985 325 eta with an M50 and ZF320. Rear differential from en E28 with LSD and 3.73’s.
The car is a canyon carver/maybe occasional track day car. I don’t need to daily it.
The 3.73’s are just too short. 1st is almost useless and I am in 5th at about 45 mph (unless I’m driving hard). Highway speeds are well above 4k.
Looks like a lot of the E36 crowd goes with 3.25 and I know the M3’s had a 3.23. Could jump to a 3.46.
Anyway- I’m not having much luck sourcing a complete 3.25 LSD. Any tips on where/how to find one? I’m close to NorCal so should be able to find one.
I also considered buying a ring and pinion and having a local shop install it for me.
Thoughts on ratio or sourcing?
