It does looks like a LSD differential, as far as what gear ratio it is.....! I don't kow...

 

Why don't you just make a reference mark in the diff vs. the ring gear, do the same in the 4-bolt flange; with your hand turn the flange as you count revolutions until you complete one full rev on the ring gear, then divide the numbers and that will give you your gear ratio!

Yep that's a LSD differential. Simply count the number of teeth on the ring gear, divide by the number of teeth on the pinion gear. There's your axle ratio.

Does it have the tag on the back? If it hasnt been rebuilt with a different gear ratio it should say. Or just count the teeth as stated above. If your looking to get rid of it id take it off your hands

Out of a 95 m3 most likely. Worth about $200 on bimmerforums.com
