Powerslot+Hawk pads=best bang for your buck(lol how many times have I said this phrase in the past week?)
As for breaking them in, I dont know what reg98teg is talking about but you're supposed to "seat" the brake pads..meaning as the first time you put them on you need to perform straight line braking manuevers progressively harder up to about a 60mph full panic stop to properly "seat" the pads. Start at like 20-30mph roll and brake gently to a stop. On the second run increase the braking force. And then after that increasing brake pressure AND speed upto about 60mph using full ABS lock(if you have ABS). This practice is called seating the brake pads and I learned it on Hot Rod television.
Or I could be TOTALLY wrong, but if I am someone will correct me.
