What else can cause the lower control arm to touch the rotor?

OK, I'm pretty much at a wits end with this car and its myriad of problems. The latest is one that has now happened on both sides of the car, but happened pretty gradually. I've found the lower control arm to be touching the brake disc. It's not hugely pushing into it, but is making an indentation in the disc and I'm a bit wary of driving it right now.

I ghetto-rigged the passenger side by using a spacer inside the rotor and then using washers to space my brake caliper bracket accordingly, but it started happening on the driver's side too. Thought it might be the wheel bearing so I changed that out but it's not made a bit of difference. The only other 3 things I can see causing it are:

1. Lower balljoints going bad (but they seemed fine when I replaced the boots on them).
2. Camber somehow coming into my car from something loosening (not sure what though).
3. Voodoo

Anyone else have any other ideas? Am probably going to use a spacer and washers on the driver's side for now until I can work out what the hell is going on, and possibly get my alignment checked next weekend. But if anyone has any thoughts on other things to check I'd lover to hear the,

Thanks in advance

I think you have it right, its either the camber, or the lower ball joints or lower control arm bushings maybe? I don't see how it could be anything else
