Yeah... 92 harness and DME will not work on the 3.0l. Well... I guess I 
shouldn't say WON'T - That's one of our specialties, making things that 
"don't" work, WORK.  But it's not what you want. You'll need aither a 413 or 
a 506 DME and matching harness from a 325i or 95 M3.

He wants over $60k for this car. Wow. Seems they made about 8,000 of these
things. Makes me wonder why nice E28 M5's aren't trading for much more money
than what they bring. They made only about 2,000 of those, and they were
also hand built. I know a guy in town here that has an 88 M5 with 15k miles
on it. Unfortunately, he will not part with it right now. Damn him. :-)

I think he's trying to get that $$ figure b/c the Z1 was never imported into

how many miles can you put on it?

On a tangetially related note, I know that Deloreans are VERY prone to the odo 
wheel breaking and that this one reason why you see so many very low mileage 
Deloreans.  From what I understand, it is VERY difficult to keep the odo 
working properly, and most owners simly give up.
 
Back to more BMW related teach, my concern (if I owned such that Z1 and 
disabled the odo) is NOT the Federal Government, but rather my insurance 
company.  I'm SURE they would have something to say about it if the car was 
ever in an accident.

Why do you say this?

On all the recent cars, the odo is digital and if the accident is any 
degree of seriousness, the tow operator or the body shop unhook the 
battery, doing the same thing . . . .

Now, now - I wasn't advocating tampering. Perhaps you could simply drive in 
reverse?

Of course, if the Z1 has the same type mechanical odo as my E28, the gears are 
probably missing a few teeth already.

        bmw digest <[EMAIL PROTECTED]>
Subject: Re: 95 vs 96-9 E36 //M3 control arms and bushings
Message-ID: <[EMAIL PROTECTED]>

Barry,
A little history as I know it (please feel free to correct!) which will help 
explain my 'summary' below:
In '95 US spec M3's, BMW added positive caster in two forms.  First with the 
upper strut mount moved rearward as much as practical yet with a centered for 
camber geometry.  Second with an offset in the lower control arm bushing on 
otherwise 'standard' geometry control arms.  Note: caster induced from the 
upper strut mount is virtually identical to '96+ type strut mounts, only the 
camber position changed.  

In '96+ US spec M3's, BMW replaced the offset control arm bushing with a 
centered style solid bushing (better all-round performance than the offset 
design) while changing the geometry of the control arm to maintain the 
same/similar total caster.  Also, the upper strut mount was changed to allow a 
slight positive direction camber offset perhaps to counter the control arm 
change, or perhaps for other reasons.  This is why you hear of people 
exchanging the '96+ M3 upper mounts side for side to increase negative camber.

One of the differences in the control arms is the geometry between the outer 
ball joint and the control arm bushing.  The '95 type has less built-in caster 
than the '96+ type. 

So, to retain BMW intended caster and camber settings of an e36 M3, the three 
components work as a set.  I.E. keep all components either from a '95 M3 or 
from a '96+ M3.  If you want to change the settings from what BMW intended 
(could be many justifiable reasons why) you could mix-and-match these 
components to alter caster/camber within factory available parts.  But that's 
for you to experiment with.
If you put '95 M3 offset bushings in the proper orientation on a '96+ M3, 
you'll have an increase in caster (don't forget also an effect on toe and 
perhaps camber).  If you put '96+ control arms on an otherwise '95 M3 front 
end, you'll increase caster likely in a similar magnitude (also with an effect 
on toe/camber).

Summary:
As far as "What is the best set-up?".  Of the two you described, I would expect 
a negligible difference in geometry with slightly (perhaps not even noticable) 
better ride and performance of the '96+ type set-up due to the centered 
bushing.  It might also be less expensive?

Hope that helps.

Cheers,
Chet Dawes

The 95 M3 has offset CA bushings and a strut shaft that's longitudinally
centred in the bearing plate (hat). These combine to establish the specified
caster angle.

The 96+ M3 has centred CA bushings (reduces caster) and a rearward offset
strut shaft axis in the hat (adds caster) for a net increase in caster.
However this newly centred CA bushing would also have the effect of moving
the road wheel slightly rearward, so the 96+ CA incorporates a dimensional
change to compensate for that. I've never measured them, but I've read that
it's on the order of 10mm at the wheel.

Normally it would seem a good idea not to mix and match these components
between the years, but of course one might choose to do so to achieve a
particular result. For instance most adjustable camber plates are forced to
sacrifice some caster in order to allow more negative camber. I suppose that
on a 96+ you could get some amount back by adopting the 95 offset CA
bushings plus the 95 CA's.

Note that using offset bushings with 96+ CA's tends to move the wheel far
enough forward to cause clearance problems, especially with aftermarket
brake ducting. Ask me how I know...

How much caster do you want?  How much is optimal?  From the various posts
here, it seems like the '96+ has trail offset in the strut to allow a lot of
caster angle without too much trail.  Seems to me the '95 got the quick fix,
and the '96 got the better solution.  I'd have to think seriously about
mucking about with BMW's design.  So far no one has offered a reason to
deviate.
