Aligned the car tonight, as it was rubbing lightly still. Went autoXing last Sat in the old wheels/tires, as it was also really cold and I didn't want to take a chance in 38 degrees on non-broken in tires.
Anyway, dialed in .5 degree more negative camber on the rear and .7 more in the front. Rear is now about -2.0, front is now about -2.2. Set toe to be just a touch (0.10mm) toe-out in the front and just about a touch toe-in (0.10mm) in the rear. Drove it around just now and it feels fine. Turns right in. No more sounds in the rear, do still hear a bit of a rub in the front, but inspecting the fender, it seems to be all rubbing the plastic guard inside (which is OK by me, as long as it's not the metal).
Have a sneaking suspicion that the rear toe might not be quite perfect at zero, but I will recheck everything later, after I drive the car a bunch.
Gonna try to get some mudflaps up in that MFer.
