Does anyone know anything about hub bore? I assume it means the diameter of the hub hole in a wheel but is that going to matter on the BRZ? I see a lot of 56.1 on the wheels I am looking at but there is also a 73 option. I assume that is MM? Any knowledge would be great, or maybe a website for dummies....?

It will matter if you want to fit aftermarket wheels on the BRZ. Not sure what the BRZ's center bore is but if it's too small you can always get plastic adapters that just slide on the hub. I wouldn't worry too much about it.
Hub Bore/Centerbore:
The centerbore of the wheel is the machined circular hole on the back of a wheel. The centerbore opening is machined precisely to center the wheel on the hub of the vehicle.
When mounting wheels, ensuring the wheel is perfectly centered onto the vehicle’s hub helps to minimize the chance of vibration. Accordingly, it is important to understand the centerbore measurements of a wheel.
- If a wheel has been specifically designed for a given vehicle, it will generally come from the manufacturer with a bore machined to the price hub of the given vehicle.
- Mass-produced wheels are intentionally designed to fit multiple hub sizes. These wheels will require the use of a use a centering ring system to reduce the bore size and accommodate smaller vehicle hubs. A centering ring (or hub ring) is a hard plastic or metal ring that fits between the wheel and the vehicle. This ring helps to center or and allow the wheel to match different hub sizes.

The centerbore of a wheel is the size of the hole in the back of the wheel that centers it over the mounting hub of the car. Some factory wheels have a centerbore that matches exactly with the hub to reduce vibration by keeping the wheel centered. Wheels with the correct centerbore to the car they will be mounted on are known as hubcentric. Hubcentric wheels take the stress off the lug nuts, reducing the job of the lug nuts to center the wheel to the car. Wheels that are not hubcentric are known as lugcentric, as the job of centering is done by the lug nuts assuming they are properly torqued down.
Centerbore on aftermarket wheels must be equal to or greater than that of the hub, otherwise the wheel cannot be mounted on the car. Many aftermarket wheels come with "hubcentric rings" that lock or slide into the back of the wheel to adapt a wheel with a larger centerbore to a smaller hub.[3] These adapters are usually made of plastic but also in aluminum.
