I've read that some people are running the same wheels & tires without rubbing, but at least one of them is lowered. Is lowering the key, or might there be some other variation at work, such as different camber plates?

This is a function of tire diameter and width combined with wheel offset. I had this problem on my M3 with Nitto NT-01's and the only solution was to run narrower or smaller diameter tires, and there are 275's that take up less space. What tires are you running on what rims, and are you running spacers as well? The problem is caused because the distance from the center of rotation of the strut to the outside corner of the tire is too long, and as you turn the steering wheel it sweeps an arc that intersects the liner at the back. You can fix it by moving the tire in (less offset), using a smaller diameter tire, or a tire with a narrower tread face.
If this is happening only on the passenger's side, there's a possibility that your windshield washer fluid reservoir has come adrift. It's mounted behind the wheel well liner at the back, and if it's come off its moorings then it pushes the liner forward and it will rub against the back of the tire when you turn the wheel.
If that is the problem, remounting the reservoir and reinstalling the liner will fix it, but when I had the issue, the reason it was loose in the first place was that the suspension would flex back under hard braking (track use) and the tire would hammer the liner and knock the tank loose. So the fix didn't last past the next track day.
Lowering won't change anything.
