If you are looking for an upgrade I would get rid of those stock Nissan made for Joe blow pads and get some real pads. I'm sure John C could recomend something good. Running more pad (Toy) and the stock solid rotor isn't reslly much of an upgrade. The Toy calipers aren't going to do much either if you ran them with cheapo pads too. I have run the Toy calipers. The pedal felt fine, not soft. Even with my, at the time cracking rubber lines. Maybe you have some air in there.
