Differential Cover
I was looking around at E36 (M3) related stuff and saw this.
Anyone ever make or thought of making this for an FD?

Not that I know of. Dunno if it's really possible, as I think the diff mounts are built into the cover, so it's a pretty serious stressed member, not just a cover. Not 100% sure on that, though.

I know E36 M3s have some problems with diffs. I thought it was due to a manufacturing defect (bolts backing out) but they may also have a problem with oil temps under track conditions.
I thought M2 was running an oil cooler in their FD diff. The cover pictured appears to be attempting more cooling via the large fins on the bottom, not as effective as a dedicated cooler but it probably gets the job done without the hassle of an external cooler.
It is relatively easy to design a cover like that, you'll have to pay for a mold, which shouldn't be too expensive for a FD design similar to that one.
The problem is no one needs it, or at least no one has talked much about premature diff failure due to oil temps. It seems the only diff failures are related to drag racing.
