The HPS worked fine for me for street driving on the stock brake setup. The rotors look fine too, but I'm not hard on brakes on the street, I tend to downshift and come to stops slowly. I even used them for a several light trial sessions at the track, but again I was really easy on the brakes.
That whistling in that XP10 video is annoying. I assume that's only under light braking when cold?
This seems to be one of those questions where you ask 10 people and get 10 different answers. Everyone says someone else's favorite sucks for some reason
