IF you swap to the abudant years 05/06/07 you will need the struts and 5X114 wheels.

Also to swap the rears require a special adapter either way you go

to be clear 05/06/07=5X114 hubs
04=5X100

so if you get 04 calipers you are good but need a special bracket for the front ( i assume strut doesnt matter)
if you get 05/06/07 the likely years, you need new rotors=not cheap, strut, and adapter for the rear

at this point you really probably want to go 5X114 and you are going to pay a lot of money for a USED BBK

You are NOT swapping the hubs. There is no need to. The STI caliper bolts onto the KNUCKLE. The 04-07 STI *CALIPERS* are exactly the same (and 04-12 all work) and bolt directly onto the WRX Knuckle, and the BRZ knuckle.

You need new rotors for any year STI calipers as they are spaced off the knuckle to accept the larger 12.8" STI rotors. If you skip that part you won't have much brakes at all.

This has already been done on a BRZ without changing knuckles/hubs by Greddy, just using 2004 STI rotors.

I've seen two stories for the rear.. first is:
The rear STI calipers from an 04-07 also bolt right onto the BRZ, but you won't have a parking brake (due to the drum parking brake used on the STI vs the BRZ using the sliding caliper).

Second is:
You need 08+ STI calipers and redrilled 08+ STI rotors.

Greddy already did both ends of the car, without changing the knuckles or using any special adapters/parts.

Personally the expense of the parts outweigh the need/benefit for me, especially considering the potential caliper issues (differential-bored piston/bleeder issue). The newer LGT fronts are almost as large (12.4"x30) but can use a simple sliding caliper. Yeah, not good for looks, but they work fine.

Even the stock brakes are made for cars weighing in at 3200-3400lbs or so, they will be awesome in this car on track IMO.
