So here is a sneak peak at what we are building.  Not only does it narrow the rear track but it also allows us to do some camber/toe progression changes.  It's still in it's infancy, we haven't checking loads or figured out how exactly we are going to hook the heim joints to the main beam (Boswell Beam) Or where exactly we are going to place the rods (race rods) don't contact any part of the body under full compression.  Also we are going to have to hook one joint on the crossmember in single shear.  Either way I can't wait to have one in my car!!!!

Wow, those look good. Will the track width still be smaller? Like you originally wanted...

Duke posted a similar style setup to that one the thread on the realm.  Me and Sam talked about doing something like that.  But before doing a more complex setup we want to see if we can get this to work.  Until you model something its hard to wrap your mind around the fine details.  it already looks like we can dial out most the toe change over the travel we use.  Time will tell though.

I had the trailing arm bug up my ass and started a thread on the realm back in 2011. We were throwing ideas around and sssr20det510 posted this.

Yeah, this is similar to the E36 M3 trailing arm.

The E30 is more of a traditional triangle.

Jeff,
If you attach the inner links at the crossmember stacked vertical rather than in the same horizontal plane, it will effectively locate the pivot point forward of the physical mounting location.

By doing this you can reduce the amount of toe and camber change as the suspension travels thru it's range of motion.

Dave,

We looked at doing just that. The problem is it necessitates a complicated mounting block or cutting and welding on new pivot points.
We wanted it to be more "bolt-in" this time around which is what the axial pivot points provides. We decided if we were going to go that far we would just make a new crossmember and put all the points wherever we wanted, maybe next time.

As far as camber and toe, we're able to change the progressions by moving the mounting points on the trailing arm since that is free for us to change. It's not as effective as moving the inner pivots but it lets the kit remain "bolt-in."

More updates!!  I'm sure some of you guys got to see this at Canby, but for those who didn't!  We also test fitted the arm today.  It worked out better than we expected, it will require cutting out the nub off for center the stock spring.  Which we didn't care to much about.  as of now it almost goes as low as the stock arm.  Maybe an 1" off.  With a slight design change we should be able to get where we want to be.  Now for the pics.   O and this is a 14x8 -6 Star shark wheel (my favorite JDM wheels so we had to borrow one from Dillon for test fitting.

I didn't Sam did :)   I worried more when it was a sheet metal arm, if the length is changed on a 100% sheet metal arm the distance can't change and they are binding.

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

I have seen a few of these designs. 

 

I had a similar one drawn up but I made the sheet metal arm come from the inner mount and the turnbuckle links mount to the outer shear flanges.
