Camber adjustment with IRS

[juse]

When I said;

"So I could weld an eccentric adjustable fixing onto the springplates connection holes (similar to the one on front controlarms inner mounting)?
I have understood that Porsche 944 uses something like this?"

I meant that could this eccentric adjust camber/toe as it does on 944?
This wouldnt change the ride height, but the angle of the line that draws trough trailing arms connections compared to tire.
And for clearing the subject; I am talking about camber here, nothing else this time.
