Looking for help on determining wear level of my 75% LSD in 320i. Want to test it out on the bench since it is out of the car. I see posts in the Porsche forum with values of 15- 35 nm for torque before slip. Anyone have numbers for the 320 diff? I have this in my M320i (1981 320i with 1989 2.5 L M3 engine) which is used for racing. Thanks!
