Thanks for the feedback. Stoptechseems to be a safe bet. They have 2 products, their Trophy kit looks impressive. I wonder why do they use external dust boots that can't handle heat genereated at the track on their base product. AP kit seems bullet proof.
Good point on the pads and rotors, I am going to look into these some more.
