Did you ever run the HC800+ with OE rotors? Identical tires with identical heat cycles and pressures? Weather? Telemetry data? Was the spare out of the trunk? When was the last alignment? Cross weights? How long since the last damper rebuild? Did you have a good breakfast that day? Hydrated? How soon did you back off due to lack of confidence in the brakes? Did the tires get up to temp before you did that?
I'd say it's not indicative at all without a few more details. A rotor is a lump of metal and the OE ones are mass produced to the lowest bidder that meets the specs, in a bin of rotors that fit an 86 more will go on an Impreza or Forrester than get put on an 86, they're not special.
I agree with others, I'd be looking at different pads based on your description, the HC800+ aren't designed for more than casual track days and I'd bet they just don't agree with the braking style you developed on the Hawks and Stoptechs. But hey you can try out other rotors and see if they do you any good first, nobody is stopping you.
Real question: first day on the PMu's? And do you DD them? How's the noise? They're on my shotlist for autox pads but I've heard mixed things about how they DD.
