Rear beam alignment, how far out is too far?

[Adey.]

So ive had the Twingo's front end aligned and pointing in the right direction, the rear on the other hand requires some shims. It's always been this way even before I swapped the stub axles but it's never been an issue. With getting everything pucker I wanted to get it set properly. Is this too bent to straighten out as some have suggested or can I just shim it up as others have said? Your input please, also what settings should I be aiming for? Thanks in advance 👍🏻

I googled Clio 172 rear toe alignment and saved the pics I came up with, all from here on cliosport. Looks like they car really be all over the place to be fair
