Poor braking

[Apogee]

I would suggest swapping to a 1" bore MC. You have 5.37 square inches of front caliper area and about 2.47 square inches in the rear. You could play with pad compounds all day, but odds are that you will gain very little that way. Hawk HPS pads are not high-temp pads by any means and should work fine in street applicaitons since that's what they're designed for. As for the front pads, per the link you supplied they include some semi-metallic pads that should be fine as well at low temps. A little heat typically helps semi-mets, but if you're noticing little to no difference, then it's probably just a low caliper pressure issue caused by having too large of a master cylinder and/or not enough boost. If your pedal is high and firm, then volume (flow) has nothing to do with what you're describing.
