Max, that's an interesting point, but why would it make this noise right after I change the rotors when it didn't do it before?
I suggest that you check to see if that is what is rubbing. I had some rubbing there on my kit at first. It was very minor, and I resolved it with a combination of "let it make its own clearance" and caliper-mounting shims (really thin washers between the caliper and the caliper mount bracket). The shims were included as part of the kit, to be used as necessary.
There are many reasons why it might rub now even though it didn't before:
1. There is very little clearance between the bridge bolt and the outer edge of the rotor, so even a minor change might lead to rubbing.
2. Wheel bearings allow some movement besides the wheel spinning. You might need new bearings (buy cheap from auto parts store or web site and DIY; it's easy) or your brake system might have the clearances too tight to allow for normal movement.
3. No two rotors are EXACTLY the same diameter, or EXACTLY round. The rotor might not be EXACTLY concentric with the hat (and in fact, some rotors are designed such that they aren't supposed to be exactly concentric to deal with heat expansion). The hat might not be EXACTLY concentric with the hub.
4. The bridge bolt cover thingy may have turned (it's round, but you may have quietly rubbed enough to make clearance in one spot) or simply ended up in a different position when you tightened the bolt up. Loosen the bridge bolt, and re-tighten as you pull the bolt away from the center of the wheel with a little strap (put a cable-tie on it and pull with your finger or something) to maximize the clearance.
5. The caliper might be in a slightly different position if you lost or switched positions of any shims that may have been between the caliper mount and caliper. Or the caliper may have moved slightly if you undid the caliper-bracket-to-upright bolts.
