Making some more progress! Hunting phantom knocks I found several issues in my exhaust system. The overpipe flanges were not flat and even with a replacement gasket there was an exhaust leak so I filed and sanded them flush. Removing the heat shields around the overpipe and cat revealed a few witness marks where the pipe was contacting the shield. I tried to wrap the pipe and reinstall the heat shields but couldn't fit both so I only used exhaust wrap on the overpipe. The cat I was able to wrap and use the heat shields. After reinstalling everything the car was noticeably quieter from inside the cabin.
While I was under the car I replaced the front black plastic panel and fabricated some replacement tabs for the bumper that had broken off.
My tuner responded very positively to the logs after all these changes so phantom knock is getting crossed off my list. (hopefully for good!)
Installed EBC slotted rotors with EBC yellowstuff brake pads and Project Kics wheel spacers.
Installed a Funk Motorsport turbo blanket.
Picked up a damaged Seibon FA style hood from OfferUp and have been prepping it.
Lots of sanding later.
Fitted to the car.
Installed Aerocatch hood latches.
I'm getting my bumper replaced by a bodyshop and they're going to finish the hood for me.
I've got a BLITZ oil cooler on order from Japan and after that I think it'll be wheels and tires.
