Here's the problem, as has been explained on here many times already.
STI calipers are differential-bored. So the leading pistons are larger than the trailing pistons. When mounting on an STI, which has them mounted rearward of the axle, the leading piston is on the lower end of the caliper, and the bleeder is at the top. When you mount that to a BRZ, which has it's calipers mounted forward of the axleline, you have two options:
1. Keep the left caliper on the left side, and the right on the right.
2. Switch L to R and R to L.
The problem with option one is that the bleeder is at the bottom of the caliper, so you'll never get a good bleed.
The problem with option two is that the leading piston is now the small piston and the trailing is the large piston, so the brakes won't work as well as they should.
For those reasons, a post of "Work? Not really." is accurate. Will they technically work? Sure, will they work correctly or as well as they should? Not at all.
In any case, will they be an improvement on the street in terms of performance, absolutely not.
Feel, modulation, yes, but if you are an ABS braker, it'll stop just the same as stock brakes in the same distance given equal pads.

WRX oriented brakes are going to most likely fit. the car uses the same brakes currently found on wrx's. so anything that is made to fit a wrx...should essentially fit the brz/frs...but it's not confirmed.

Couldn't you go with option 1 and use a reverse bleeding technique such as this:

Did you read what I quoted? It would seem that there are 2 reasons why they would not be a good idea.
