Update: I performed a double bed-in for the street pads (Porterfields) tonight. These pads are great. I pushed them close to their limit to see how fade resistant they are, and I was impressed. When they are at typical stop and go temperatures, they are very quiet and have excellent modulation. The kit definitely gives better pedal feedback than the stock calipers and threshold braking is effortless. It's a shame Porterfield does not make these pads in stock caliper fitment because they are much better than Hawk HPS in almost every way.
We are having a freak heat wave here, but if temperatures get closer to freezing again I'll comment on how the pads perform when they are dead cold.
Overall I'm very pleased with the caliper kit so far and it's what I expected: better pedal feel, improved fade resistance, awesome pad options
