Camber for ford fiesta ws?

[Beastfiesta]

Ok so I have a 2010 ford fiesta ws and I am wanting to get as much camber as possible.
I have a tiny little bit of camber atm with my solid rear but I've been told I won't get any more then that unless I re-do my rear end.
Because it's a solid rear I can't get camber arms and I was wondering if anyone has a solution?
Or if anyone knows if another ford around the same size has I dependants that will fit? And if so would that even work?

If I've left anything out just say. Please only serious answers
