I got them on sale from Fred Beans I believe (coupled the order to make it worth the shipping). To be honest, I haven't tracked them yet, and that is the major reason I finally installed them (had them for over a year, and the stock brakes just last forever...). I can't say about heat fade once they're on course, but they honestly seem to grab more quickly.
I needed new brakes at the time, but the dealership replaced stockers for free so I held off on the install. I'll give you an update once they have been put to the test
They don't squeal like harder pads though, so for street use they are great so far. Longevity will be something to ask a member who has used them for awhile though.
