    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.

    I would like to... In fact, I already have heat-proof STi decals I ordered from eBay, but I don't have an easy way of taking off the wheels to get at the calipers right now. I may have to wait until I get new wheels installed (unless someone who lives close to San Fernando Valley, CA, can help me with this, wink, wink!)

    The new Brembos don't give me any more stopping power, but what it does give me are: (1) more initial bite so I don't have to depress my brake pedal as much as before, (2) total elimination of the "mushiness" I felt with the stock brakes, and (3) increased confidence in my brakes which enhances my driving experience especially when I do canyon runs.

    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.

    This must be some inside joke I'm unaware of.

    Thank you!

    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.

    I believe the master cylinder only needed swapping in the previous generation...as the OP says, it seems to be the same.

    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...

    Easy way? How hard is it to pull out your jack, break loose your lugs, crank it up a few times and pull the wheel off? Anyone can do this anywhere!

    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...

    Kool. I did the upgrade on my 07 but I had to get special DBA rotors to match the parking brake drum pad. I just took an air chisel to the rear dust shields. Off in 5 min.

    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.

    Very false. The 2008 calipers are the same as the 04-07 STi just not manufactured in Germany they are a cheaper version of brembo calipers but the same in every other way.

    Since this was 4 months ago the wheels should have fit by now but the grids typically need a 5mm spacer to clear brembos. Check with wheel dude. This is the reason I didnt go with them.
