Limited Slip Differential

[Bmw1990]

I need help locating a rear differential for my 1990 325i-Anyone have any good sources. I am not in the need of any high performance just OEM if possible.

Thank you!

are you positive your car doesnt already have it? i think it couldve been option on your car. but if not, i think the only oem diff that would work, with the same ratio, is from the M3. Your stock ratio is 4.10:1 and the iX is out due to the AWD and viscous coupling, and the M42 318 is out because it uses a smaller case

Donor can be any of the following with the wanted ratio and LSD.

Your ratio is on a tag on the aft face of the differential.

E30-6, E24, E28, Z3.

My car has it, but there is an problem with the oringinal one. It already has a limited slip diff., the only reason I asked for one, is because i was wondering if anybody knew where I could buy one. I have been looking all over the internet, all i have been finding are high performance diifs. that are in the thousands of dollars. So if anybody knows where i could get one let me know. thanks
