I use Hawk Performance Ceramic on brembos so not a direct comparison to HSV callipers but close enough for a response to this question. I think they are a great pad with good stopping power, long lasting, very low dust and they do not cut grooves into the discs. They are probably similar to EBC Reds which I quite like. I've tried EBC Greens and do not like them at all. There is a brake pad thread somewhere on this site.
