    Went nowhere. Ended up selling the car for scrap.

    I'm doing an e36 track car now, since it comes from the factory with a non-stoneage rear suspension. :)

    it may just be easier to fabyour own subframe ratherthan fab the car to fit around an existing subframe. I would love to see this project completed.

    please keep us updated. Also i would love to see some ohlins in the stock rear shock location mounted to a double wishbone. this reduce unsprung weight dramatically as well as giving much better camber gain and toe control as well as adjustability.

    as far as a front suspension goes... i dont think you can get much better than this

    That cars a honey but the url you pisted was a disappointment - why? cos i thought you'd already found an e30 with a miata arse end...

    all we need is some italian stuff in the car and it will be the whole WWII axis:hitler:

    vertically, i imagine there to be an issue... bmw framework being a little low for example.

    The actual miata rear subframe is AWESOME. It will be cake to connect to the back of the e30. The diff/driveshaft is what I'm worried about.

    I would not say the miata chassis is particularly overbuilt.

    maybe you plan to remove a bunch of overkill mazda designed into the structure while mating it up to the e30?

    1999 Miata rear track width - 1430mm
    1991 BMW E30 rear track width - 1424mm

    Pretty darn close...

    I am interested on how you tie this all in to the new cage / chassis. Sounds like the rear of the car will become a tube frame. :)

    I'll probably have to redo the rear shock mounts. This whole thing is going to be installed in conjunction with the cage, so the body will basically just be the body at that point.

    How close is the rear shock / tower mount placement compared to the E30?

    Looks like a Miata rear unit. I've been looking into one as a fun little DD.

    I think I've changed my mind about this.

    I've found something else that may work a little better and be a lot easier than a whole custom rear suspension.

    Sorry to keep posting nothing but teasers... I'll try to get some pictures to post soon.

    Here's a big picture.

    Can't wait to see what you come up with.

    Well, I've made some progress with this...

    I'm going to use e36 hubs. Easy to get, cheap, and you can put all kinds of brakes on them.

    The rear subframe will probably look a lot like an e36 one also... but that's still in the works. I'm also still thinking about cutting up e36 rear trailing arms for the uprights, but I'm dead set on using the hubs and wheel bearings and such.

    Hopefully I'll have some time to get started tearing into the chassis I'm going to use for this soon.
