Installation:
The old calipers are mounted with the "bracket" outboard
(bolt heads behind hub)
The Brembo bracket has to be
mounted inboard, (bolt heads in front)
I've located a copy of the
installation instructions here:

Now
with this, the Brembo bracket will be the nut, it's aluminum and the factory
torque for fastening the caliper to the upright needs to still apply.
Once
I've confirmed this, I knew I have to use 59 ft lb, into an aluminum aloy piece.
The bracket is a bit weird. As you tread into it, it acts like threads may
be tapered, the deeper you go, the more it locks the bolt. This is my
observation, I was not able to confirm it.
I was however able to confirm the
part number, which is printed nicely on it. It is the right one for my car. So
whatever features they built, they meant them for my WRX.
The next thing
is that the bracket is not symmetric.
You can see in the above
picture that one side sticks out at the mounting points. This is how it needs to
be installed.
The instructions have you remove the dust shield unless
there is a 3mm rotor-shield clearance all around. In preparation to this, I've
read the Subaru factory repair manual, that shows the shield not coming off
unless the hub is pressed out of the upright, like for bearing
replacement.
So I prepared to cut the shield out.
I found that my
early '02 had a different shield, much smalled and it did not go full circle
around the hub, it was half-moon style. I could have removed them, but with
couple hammer blows, I've obtained the 3mm clearance and decided to keep them in
place.
