they work great i also installed them with fresh brake discs. no sound yet. decent bite at any temperature. I switched from Carbotechs (previous install) to these to be more road friendly. Overall I'm satisfied, but next time I'll probably use a higher temperature and a firmer surface. They feel a little softer on the brake pedal than I would like/I'm used to. This is an amazing outdoor playground. although I wouldn't call it a dual purpose site.
