Both the standard and outboard braked rears on ERA cars like 1/16" of toe-in per side. The standard rear is not adjustable for toe, so you have to just cross your fingers that the LCAs give you zero or a hair of toe. The outboard braked rears are adjustable for toe. I never heard the "wanting to toe-out" on acceleration thing. Remember though that the outboard braked rear has an angled-in trailing arm up at the top of the upright as well.

I think he said he has a Backdraft....that's BMW, The BMW suspension should go up and down without altering the toe, an alignment machine should fix it

The jaguar rear tow is adjustable at the shims behind the control arm pivot rod mounts at the bottom of the diff. You gotta set it up...it takes a little time.

I know, but I spent a good ten minutes looking and I can't find any posts anywhere on the 'net that say acceleration can cause toe out. I think what the elves told me is more in line with the physics of these cars, be they Backdrafts, ERAs, or CSX cars.

Another five minutes turned up this seemingly definitive youtube vid. And you know what they say, if it's on youtube, then it has to be right.
