Notes
2002-05 cars: reported to need an adapter bracket (sources name Kartboy and a KNS-005 bracket). 2006-07 cars: reported to use the existing brackets with no adapter bracket; one vendor notes the Brembo bolts have a different thread pitch than stock. Both generations: the smaller WRX parking brake needs a solution (adapter rotors, or KNS-800 shoes per one vendor). Community/vendor reports only; not manufacturer verified.
