Calipers are getting casting markings shaved off.
Pistons were shot, so I ordered 8 new OEM replacement pistons and a rebuild kit for Z32 calipers (I think they're the same).
Also ordered 48mm Muteki "titanium" colored lugs, EB48 cupholders, and OEM Nissan metal center caps.
Got this horrible screeching noise that's been happening for a few months, sounds like metal on metal contact. Thinking it's either something to do with my transmission or t/o bearing, or a seized caliper somewhere. I'll pinpoint it when I do the 5 lug and brake swap.
