Six Speed Trans Options

[Yo.goob]

Has anyone confirmed any other rear differential fitments aside from the stock E30 diffs? Looking for the best option since I'm using the GS6-17bg and no longer using the small case 4.10 that came with my 318is.

I know Striker01 using a custom shaft significantly simplifies the need for any other modifications to the rear diff, just not sure if any other options exist

I don't know, using my stock medium case.

If you're keeping the E30 subframe, then you're pretty much tied to the E30 case- the flange ears on the front of the diff are unique to the E30.
