Styling Rear camber on lowered doblo

[simon_16vpunto]

I would like to lower my 71 plate doblo L1.

Is there anywhere that sells camber adjusters for the rear, as when the van is low, with weight in for example, the rear wheels point inwards at the top.

It doesn’t look too noticeable on mine, as I have big wheels, but I have noticed on a few vans with standard wheels it shows really badly with heavy stuff in the back, and I don’t want my tyres to wear out on the inside.
Also it looks stupid with camber.

Thanks
