An easy way to determine if your car has a LSD is to raise one rear wheel off the ground and with the transmission in neutral, spin the raised wheel with your hand. If it spins freely, you most likely have an open differential. If you feel resistance, you probably have a LSD.

Another test is to lift both rear wheels off the ground, put the transmission in gear, and turn one of the wheels by hand. If the one on the other side rotates in the opposite direction, you most likely have an open differential. If they rotate in the same direction, you most likely have a LSD.

With one wheel fixed (someone holding it in this case, could also be on the ground), either in neutral or in gear, it is very difficult to turn the other side at all, but it will turn given enough force.

See if you can try these.

Another "test" of LSD.

what is your question, are you asking if it is an LSD, or are you asking for the ratio?

I know it's an LSD. I believe it's originally out of an e30 with some funky welding for the 6er application.
The ratio is what I'm looking for?

they are my role models

WOOO to the 535i!
rocking the e28 BIG SIX!
sorry i cant help you with this but hopefully i can help you with any future questions, post or private message me ( or even IM me)

Does this make it sound like it might be a 4.10?

that makes sense to me!

why do people find random old threads and post stuff on them??
