I thought the base fuel is the same from several refineries. (4 in CA?)
They just add diff additives to diff brands of fuels if so required before delivery to the gas stations.
I believe BC Racing is a Taiwanese brand.
You can custom order to your liking.

They also make forged wheels.
BC Forged.
Tire pressure PSI.
PSI * sum(contact_patch_areas) = vehicle weight.
If the tires are wider (i.e. bigger patch area), PSI usually gets lower. The new Z has pretty wide tires.
Owners can adjust PSI to fit their needs.
The system on my Mazda had that issue in early days. It was due to software glitches. The time it took to come back is when software reboots itself.
My guess.
Still waiting for my Z after 2 yrs.
Installed one myself before (Gentex).
It needs three connections: ground (body frame), constant 12V (for Homelink) and switched 12V (for auto-dimming).
If you buy one as an OE accessory, it should come with installation instructions. If not, you need to plan on how to find the 12V tap points...
I installed a set on my Mazda CX5. They are easy to DIY.
It lasts about 4-5 yrs. Then, replace the button battery inside, which is also easy to do.
They are getting very expensive. I had it for $200-300 bucks back in 2017.
It costs about $500 nowadays.
To OP, if the front end was not hit, then, it could be a warranty repair.... you can argue that.
That's Donalex's point, I believe.
The video said, it was "rebuilt"... the parts they used.
