Given the way the toe is adjusted on the rear of a Stratos (Lancia, Hawk & Corse "I") then is is fair to assume that with the symmetrical reverse lower A arm design then with the correct amount of toe in applied you would find that the rear strut is actually vertical?
For every adjustment of the rear toe then the strut will alter in angle but with toe in applied it will pull the outer end of the wishbone forwards which would bring it back into line with the top mount?
The strut top being set forward by 23-25mm relative to the wishbone bracket could make sense in this case?

I can see that, but is the pivot point for toe-in not the rear of the tie-bar, so the forward movement of the strut on toe-in will be limited?

Good point re toe adjustment moving the upright forward, hadn't really taken that into consideration. Just did a very, very rough sketch (and I've had a couple of beers) and to get the upright to move 25mm forward i think you'd end up with something crazy like 20mm toe-in across the car. So i think even with a reasonable amount of toe in on the rear and the arm spaced as far forward in the pickup point as possible you'd never get a fully vertical strut, not that that is necessarily a bad thing, with a spherical bearing or rose joint i can't see any issue at all, and clearly the rubber bush also has the compliance to cope with the misalignment

Agreed, 1 degree of toe in equates to approx. 5mm of forward movement at the upright end.

The bottom pivot of my old uprights wasn't at 90 degrees to the strut mount, saying that, you'd expect them to be a handed pair but mine weren't, they were both identical, once fitted it was all a bit weird.
