Didn't do anything further last night, got the undertray and front bumper on this morning. Undertray has all the fasteners on it for the first time (some were missing). Zip-tied my boost sensing line in the engine bay. Scouted around town for an air filter but no one had what I needed, so that got ordered. This evening I put the fan back in under the dash (removed it to run the boost sensing line), did the sagging glovebox door fix, and installed new rotors/pads all the way around. I'm happy to report that I had no issues with any of the pins on the calipers, all were clean and had some lube on them.
