I personally have not had any experience with the Metal Masters brake pads, but when it came time for me to get new pads, the overwhelming consensus was to stay away from them and get AEM instead. But seeing as how you already have the pads and the blanks are brand new, slap em on and let us know how the setup works out. Worst case scenario, you'd have to get ur rotors resurfaced at your next pad change. But if you can swing it, get the AEM pads, I've had em for a while now and couldn't be happier!
