Silver Fox 43 Report post Posted November 24, 2008 Riley, you need the diff out of a E28 525e, usually 2.93, 3.07, or 3.25 med cases. Just change the output shafts and back cover and clutch pack and off you go. Quote Share this post Link to post Share on other sites

drifty325i 0 Report post Posted November 24, 2008 Yo Riley You should investigate to see if you can swap over the crown wheel and pinion from a regular NON LSD diff that would means heaps of ratio options and a brilliant chance to fit more clutch packs for higher lockup Seems like a better way to do it than fitting a large case diff I don't see how BMW would make the med case diff totally different in design just because it was an LSD, only the center should be different. We might have to check into this more Jimmy, pretty sure that guy i no has a 535i with the diff. I no the diff looks very different however the guts might be the same??
