What's the best rearend (Diff) for M60 swap?

Just remember that a V8 automatic in the E30 requires fabrication work to the trans tunnel, it's not just a bolt-in affair. The 5 speed automatic is a humongous transmission, even compared to the 6 speed manual, which is a big transmission. The manual transmissions are a much "friendlier" swap... in case you weren't aware.

Mine is a 5 speed auto, I didnt have to mod the tunnel. It is tight in there though!

I also use a 2.93 LSD, it cruises beautifully on the highway with that ratio.

This is awesome.
Getting info like this from all of you before hand is priceless.
I just picked up a*300mm.de swap brackets for the M60 including the optional 20mm sub-frame spacers and extended 10.9 grade bolts.
My son is so frecking excited. the 2.93 seems to be our best bet for the direction were going in.
Now on the hunt for a good donor car in the area..
Wooo this is fun!

Bought a S2.65 from E34 525tds for my build, hope to brake the sound barrier on 6th gear. I do hate high rpm on the highway :)

i was at the junk yard yesterday. there was a 96 540 auto there. the diff was 2.81 lsd if i recall. in contrast, you can find a 2.79 in the e30 style housing really easily.
