First of all, very nice work. It looks great.
I thought a full Brembo conversion would have required a different master cylinder and brake lines?
I would consider putting the spacers in the back as well. In a performance situation, I would imagine the front wheels being wider than the rears will be a draw back. If anything, rears usually sit wider on performance cars.

The stock 17" rims do clear the Brembos in the sense that their radius is large enough to fit the calipers inside, but the curvature of the spokes is not enough for the wheel to spin without scraping the calipers. Not only am I getting 18" rims, the rims are of 2004 STi fitment which should ensure that they clear my Brembos.
It is my understanding that the 08+ WRX/STi share the same size master cylinder. In any case, my Brembos work just fine with my stock master cylinder and the Stoptech stainless steel lines I installed previously.
For now, I'm satisfied with running spacers just on my fronts. The spacers are a stop-gap measure anyways, just until the 18x8.5 Hyper Black Rota Grids I special-ordered arrive. Once I swap out the wheels and shoes, I'll most likely be selling the spacers and stock wheels to the highest bidder.

However on the Subaru symmetrical AWD system, larger wheels in the back is not beneficial. It messes with the correct power transfer properties if you have wider on either the front or the back since it creates more traction. Not good either way. That's why Subaru has all the same size wheels with the same offset on the car to begin with...
But what I was getting at above is that with having the spacers only on the front, you are changing the dynamics of the AWD system...you could actually be causing harm to the differentials...

The nice thing about the 2011 wide-body WRX is that so many components are the same as the STi. So most of the parts were straightforward bolt-on.
