Welcome to the nuthatch, It has been posted here before about using BMW running gear ie diff etc and I think the opinion was that using the rear suspension was out and fitting the diff etc was a pain too. The engine and box could be used to good effect and again this is on the forum with pics of a build but I cant remember who but someone will, I have a damaged 318 IS compact in the garage and am considering it for engine and box.

Good luck

I've looked at the BMW E36 bits, the E30 bits are broadly similar.

The rear suspension will require a bearing housing to be made to take the BMW bearings and to fix to an upright similar to the Sierra one, as the BMW set up is unusable.

The diff is quite big but can be squeezed in, and the same applies to the engine and gearbox, using mods similar to the MT75 ones.

The front hub isn't tall enough to be used alone and requires a fabrication like this



which is bolted to the existing strut mountings.

Hope this helps

Cheers

Chris

Andy, if you can. I would try and use the BMW rear end.
It's easy to get hubs with discs, or abs etc and as the rear carriers are fabricated it should be possible to fit them.

It seems like it would be easiest to use sierra front uprights though. i'm not sure i'd fancy the adapter doodahs bolted to the back of the BM hubs. Mind you they would look nice machined out of billet Alloy.

Cheers
Chris

Theres quite a few people worldwide who are interested in using BMW parts some specific drawings and measurements (perhaps as an ANNEX to the book) and stickied on the forum might be good.


.......please

Looking at the E36 front uprights, BMW didn't mind bolting a 'doodah' to it. The strut is attached to the back of the upright with 3 bolts. That strut has a lot more leverage than the top wishbone would have. It seems to me that a properly designed 'doodah', one that provides the desired geometry, would be quite strong and perfectly safe.
