Update on EBC Yellowstuff pads and Akebono front brakes now that they have a month or so on them:
Obviously larger calipers and rotors really only come into play when being used in a track application or when towing downhill for extended periods of time, when brake fade can become an issue, so since I haven't been around the track and don't have a trailer hitch, nothing to report here.
What I can report, though, is that the Yellowstuff pads are very capable and bite very hard. A dramatic improvement over whatever generic ceramic pads the previous owner was using. In a panic stop from 60 the engagement is violent and easily overwhelms the tires and even the ABS system momentarily. The best results seem to be achieved by avoiding a 'slamming' of the pedal and instead applying a quick and purposeful progression of foot-to-floor. When applied in this manner the pads are smooth, consistent and very aggressive. It would be interesting to get some measurements, but they certainly work. Worth noting that side effects of the pads include both increased brake dust (don't buy if you cant stand a dirty wheel), and some light brake noise when coming down from higher speeds (45-60 mph to a stoplight seems to be the loudest). To me this is perfectly acceptable, as there isn't any at slow speeds and it is a high-performance type of noise rather than the type that begs to ask if the installer forgot to use the Disc Brake Quiet during their last brake job.
Not as technical as a Road&Track writeup, but hopefully this helps if anyone is looking for new pads. I'll update again if I can take a few hot laps around the track.
Summary: Would recommend to friends who care about brake performance (but not shiny wheels), and would buy again.
