This brake kit includes a 6 pot caliper and 2 piece floating hat rotor for the front and a 2 pot caliper and rotor for the rear, 4 STI stainless steel brake lines. Both the front and rear rotors are grooved.
STI suggests that this system provides improved fade resistance and greater damping force. The kit is painted silver and does not require exchanging the wheel on the special S203 and S204 editions in Japan, but may require a different wheel on other STI models.
Because this is a sport part, designed to function on the track, is not abnormal to experience brake chatter, additional brake noise, and quicker wear rates for the pads and rotors as compared to the original equipment installed on their vehicles.
