The more I think about it, there was as minor shake before changing the rims. Do you think moving from 17" rims with runflats to 19" staggered M3 rims (non runflats) would make the shaking more noticeable/more extreme?

My rear wheels are also rubbing really bad -- way worse than they should. And the rear of the car almost looks like it is sitting lower than it should. When you say control arms, do you think I should just replace the front and rear control arms with the TRW M3 knockoffs, and get some rear M3 subframe bushings?

The ones I was looking at are here:

Sorry to ask a suspension ish question here, but you mentioned control arms and it got me thinking about how the car squats currently. I need to stiffen up the rear to accommodate the mods anyhow, so maybe this would kill two birds with one stone?
