I couldn't find a thread that speaks to brake upgrades like the wicked Subaru Seat post... Apologies if I missed it.

-----------------

What brake options are out there for SG Forester? Off the top of my head, and in no particular order;
1. WRX 4/2 pot
2. LGT?
3. STI Brembos (does 04 or 05+ matter for 5x100?)
4. STI MC/BB
5. Upgraded pads/rotors


-----------------

I'll be happy to consolidate information at the top here - just share what you know!

You can do the WRX 4/2 pots. They're a direct bolt on.

You can do the LGT rear kit, which I believe requires an adapter (might be wrong about this).

I did Brembos off of any '04-07 USDM STi. Of course, I needed 5x100 rotors to avoid swapping out hubs/knucks/axles. With that said, the fronts bolt right up no problem, but you do need to bend or drill out the dust plates. The rears needed more work. Instead of ordering specialty rotors, I opted to do it the way I felt was right, and replace the e-brake shoes with larger ones. The kit from GodSpeed brakes in the U.K. includes larger emergency brake shoes, and adapters for the calipers. The kit included every bolt and washer and bracket and shoe I needed. I think I paid like $250 for it. The rears also require a bending or a removal of the dust plate. Careful with this. I just bent mine, instead of removing them, and didn't bend them back far enough. I ended up scoring my rear rotors something fierce.

Stainless lines as specific to the caliper, so make sure you get the right lines.

It hasn't been updated in a while so is missing the SJ and a couple of upgrades available to the SH (e.g. GRB STi rear calipers are a direct bolt on with suitable 5x100 rotors from dba, RDA, Project Mu, etc.)
