I can confirm these are correct PN's as I've ordered and received the deflectors.

I think most owners are adding deflectors as potentially preventative without having had a brake issue in the first place (cooler brake temps being generally better than hotter, as long as pads get to operating temp). I'd be happy to do the same, so long as I know I'm not somehow making cooling worse than OEM (less airflow from my ducting actually getting to my rotors or perhaps interference from the air being scooped from below).
I've not heard anyone actually testing brake hardware temps. Closest I heard was one SS 1LE owner track rat who experienced brake failure and (hope I'm remembering this right) thinks he boiled his SRF fluid at CMP. Not sure which pads he was using. He then added the SS scoop deflectors, vented pistons (and maybe Ti shims?) all at the same time. He never had a problem after that (CMP or anywhere else), but also pointed out that he doesn't know which of the changes helped and how much benefit each contributed.
So would test data be as simple as a tire temp probe placed on the rotor or caliper immediately after a lapping session? Then compare temps for before vs after deflector, under similar ambient temps?

I'm looking to test soon:
Z/06 vented pistons vs solid pistons
SS Track deflector vs CT5-V BW deflectors (and maybe SS 1LE deflectors)
Waiting on confirmation for an up-coming track day though. "Data" will be via caliper temperature strips. I may also devise a "garage" test, for the deflectors, utilizing an electric leaf blower and heating the rotor for a particular duration/temperature and checking cool-down rate.
