Also, if it helps nail things down better, these particular calipers are available in either a 1.25, 1.38, 1.62 or 1.75 Bore size. If they fit, which would work best with the master cylinders I have stock - installed on #488?
All this information will help me get my car closer to putting 15s back on there without having it be cost prohibitive. Again, I really appreciate the technical assistance!

It looks like you're using our hat, so the conversion to smaller discs shouldn't be too hard. You might even be able to use your current caliper (assuming it will fit around a 1.25"-wide rotor), if there's room to move it in 1/2" with a new bracket. Your rotor number should work, but we use the heavier-style 160-11836 variation.
