    Ok well...I found out the 04 STi has the same bolt pattern as WRX's so I can use those rotors...Now does anyone know what calipers to use? Could I use the 04 STi calipers?

    From what I know, you need 04 STi front calipers and rotors. Then you need 08+ rear STi calipers and rotors drilled for 5x100

    04 STi front rotors
    STi brembo front brake calipers and bracket with hardware

    STi brembo rear brake calipers
    KNS rear brake adapter
    Rear 08 STi rotors dual drilled by KNS

    You can also buy DBA rotors because DBA makes 1 set of rotors with 5x100 and 5x114.3

    That is what you need. If you have questions, message me. Ive done this personally.

    For which part?

    Id suggest getting 04-07 Brembo calipers front and rear because they are manufactured in germany.

    The rear calipers. But that's what I would go with anyway (the German spec brembos that is).

    Doesn't matter, just get the correct mounting bracket from KNS

    Just so I clarify this a little better..

    STi calipers 04-07 are German built Brembo
    STi calipers 08+ are unknown origin Brembo, this is why the Brembo logo is replaced with STi.

    Either caliper set will work front and rear I'd recommend matching the set and rebuilding. Rebuilding the calipers is cheap, about $100 per pair. The front bolt up to the stock caliper mounting using the Brembo mounting bolts and the mounting bracket make sure when you buy used these come with the fronts.
    The rear you will need to use an adapter purchased from KNS brakes to mount the caliper. You will need to very minor modify the rear hub to fit the adapter bracket. This consisted of about 5 minutes with a brown roloc cookie on an angle grinder. Also cutting the original brake backing plate is necessary to fit the new rotor.

    Rotors:

    Front will easily use any 5x100 2004 STi front rotor.

    Rear rotors you must use 2008+ STi rear rotors and have a machine shop drill the 5x100 bolt pattern or purchase a rotor like DBA which come with both bolt patterns. To make it easy/cheap KNS brakes offers standard Centric rotors that be personally drills the extra bolt pattern in.

    Brake lines:
    No modification required. Make sure to replace the banjo fitting crush washers.

    Questions? PM Me.

    You could also do the swap with 06-07 Subaru 4/2 pot calipers. Basically the same deal just a little cheaper. The fronts will bolt right on with the same rotor. The rears will require a 2010 legacy gt rear rotor and the KNS brakes adapter. I have done this personally to my 2011.
