Hi John,
=20
My apologies for the delay.
=20
You mention this project was in boxes? Was the suspension also in boxes =
or was it a rolling chassis?
=20
Excessive rear camber, in my experience, is almost always due to =
elongation of the subframe bolt holes supporting the differential. =20
This allows the subframe arms to lower, in turn taking the trailing arms =
to sag toward the center of the chassis, and in turn the camber becomes =
excessive.
The only lateral hold of the subframe bolts is a bit of bent sheet steel =
that cannot support the bolt weight.
=20
I have photos somewhere of repairs to the subframe inner bolt holes =
where I applied a repair using heavy wall pipe with an ID that matched =
the OD of the Subframe bolts. =20
I drilled out the subframe holes using a unibit in a drill press to fit =
the OD of the pipe, cut pipe pieces to fit to the outside edge of the =
subframe metal and welded them in place. Then I suitably ground, =
painted and rustproofed the upgrade repair.
=20
Alternatively it might be weak coil springs, however that can be =
temporarily corrected by adding a machined spacer or thicker rubber =
insulators under the spring.
=20
First check however would be the subframe bolt holes. You can jack the =
car and look to see of the differential plate to subframe arms has =
shifted, a tell-tale sign of elongation of the bolt holes.
=20
Cheers!

Subject: [TR] Stag Rear End Squat
=20
Well, the Stag motor purrs, drove to the end of driveway and back (!) =
and all seems well.
BUT the rear end sags something awful, showing a reverse camber of a =
full inch. Are the springs too short? Remember I bought this project "in =
boxes" and all suspension parts were new. I don't remember it being this =
bad when I trailered it to the paint shop, but that doesn't mean much.=20
Despite the squat, the car sits pretty level, only about 1/2 inch lower =
at the rear measuring from the rocker chrome.
Could the DPO have simply bought the incorrect spring? Or is it =
something else?
Many thanks
John Howard
Oh - and cannot connect to the Stag list. Is something up (or down) =
there?
