here's a shot of the new IE diff mount.

We started work on a second rear subframe and we did what took me almost a week and a half (counting classes and other stuff) in a day. It also helped that my bud's e30 was completely stock but yeah, we did pretty good time-wise. and I even had time to take apart his brake calipers and spray them down with brake cleaner while we worked on the subframe.

There are two different E30 subframes. There is a extra support bend in the subframe tunnel on the later subframes. The switch happened in 85-86 I believe. I've seen subframes damaged like that before. I believe it happens when a car bottoms out on the diff. I had to weld the diff back into a E12 that was driving around with only the exhaust rubbing on a axle holding the rear up.

ah ok. I'd like to see an early subframe, mine and the one I helped out with were both later frames.

kinda late but yeah I never saw any marks on my diff and I'm pretty sure I would've remembered bottoming out. :( but now that's all fixed and new. waiting on a adjusting bar tensioner to get it back on the road though.
