I can't imagine why Subaru would use a different parking brake between the nearly identical platforms vs simply a larger disc that fits their standard parking brake unit which is probably the very same unit used across all their models except maybe the Tribeca.

I bet it is identical

It is -

R180 / DCCD cars (except '95 STi Ra) tend to have the Large parking brake / BIG rear axles combos but all others (? tribeca) have the same small parking brake.

I did the 2005 LGT (2006-2007 WRX rear rotor) conversion on my 2003 Legacy L-SE everything was bolt-on, BUT you have to use 2005+ LGT calipers / caliper brackets.

2005 LGT Front/Rear brakes = cheap upgrade but you need 17" wheels + they are ugly.

I use 4pots on my OBS-t with project u pads + a simple JDM STi Vented rear rotor / stock pad set-up + braided lines / superblue fluid & the braking power on my wagon is INSANE - part of my demo ride is stopping & everyone that gets in the car LOVES the brakes, I plan on doing the 2 pot rear conversion to get rid of the ugly 1 pot rear rotors. Our '02 WRX with HPS pads / always fresh fluid does not even come close to the stopping power on the OBS-t.

Common front brake upgrade in Japan that slots between brembos & 4pots is to use 2005 LGT front rotors with 300zx 4pot calipers - they actually sell adapter brackets for this conversion over there.

I have a nice set of aluminum 300ZX 4pots sitting in the garage & was planning on making a set of adapter brackets but have changed plans on this conversion as I want to stick to 15" wheels on my OBS-t which already is running Subaru 4pots.

If anyone would like to do the 300zx conversion PM me...
