Hey guys I picked up a E34 M5 full subframe/rear end from my friend who was getting rid of it. Its everything except the differential. I have the axles, hubs, trailing arms, subframe, all bushings, etc.

Whats the difference between this subframe and the E34 525 one? Is it more rugged? Will it only accept an M5 diff? Are the axles better? Trying to figure out if I should rush to put it in or hold out and get a diff and all. Its a different part number than my 525 subframe, and it looks like it has some eccentric bolts for adjusting the trailing arms, but other than that I don't have any idea what might be different. Thanks!

pretty sure the m5 subframe will be pecific for the big case diff...otherwise I am sure these (http://www.m5board.com/vbulletin/forumdisplay.php?f=4) guys will know
