Thanks guys. Would highly recommend the powder coating. Rebuilding the calipers, after figuring out the rear caliper seal issue, was much easier than I'd anticipated.
Had an incident this week. Had to run an errand about 30 minutes away, parked her for 5 hours, came back out at 8pm to find all her coolant puddled on the ground. Drove to a nearby gas station to see if she'd hold any water, which she wouldnt, so got her towed home. Finally had time to get under her this weekend and take a look and it ended up that a hose popped off from under the expansion tank. PO had the expansion tank relocated and there's a number of non-stock adapters/connections involved. Thankfully it was a super easy fix, but I wouldn't be against finding a more elegant solution to the hoses running there.
Then gave her a wash and completed the debadge by removing the side sdrive 35i emblems.
