go with this. allows you to keep the stock e30 driveshaft

if you dont want to go that route and dont have your stock DS, you can use any 4bolt DS from 96-99 m3. or one from an e36 328i.. IIRC the 4 door 328i DS works too. or if you can find one, an e30 m3 DS, which would be awesome!

Oops Im blind... +1 on the revshift. However make sure your zf tranny has the right flange that works with the revshift 24v flex disc.

Heres a pic of the flange that doesnt work:

True, True. I have a zf from a 97 m3 in my e30 swap, but for some reason i had the first on you posted. i guess it was from a 318 or something. So i had to grind it down a bit in order for the bolts to fit. Since it is so close to its rotational axis it doesnt need to be exact when grinding it down.

Took me about 20 min and it bolted right up. no vibration at all.

that item will not work for any of the Getrag 6 speed or ZF 6 speeds then

i guess it was from a 318 or something.

318's have transmission output triangle flanges incompatible with a ZF SG310/320 gearbox.

e34 525i 1991/2 m50b25 non vanos had ZF Sg310
1995 usa m3 s50b30 had zf sg310

1996-1998 e36 M3/328i had ZF sg320
e39 528i had zf sg320
e46 330i had zf SG320 in the 5 speed varients.
