Camber adjustment???

[juse]

I have abadoned the idea of using an eccentric bolt to adjust the rear camber. I dont think I need an adjustment, as my car will not be driven on track. But something needs to be done to de-camber the rear.
My friend has now this idea to raise the irs-mounts about 50mm (2"), about the same amount that he has lowered his rear. I think that should de-camber the rear tires back to stock specs. Has anyone done this before?
