If you are looking to get better brake performance than you should stay with the stock brake rotors and just up grade your pads. I have been using Hawk HPplus pads for my sa for about 8 years they aren't going to wear out you rotors fast and they have great stoping power. The bad side of them is that they do create a lot of brake dust. They are good for street/ autox use as well as light track day use.
I had to upgrade to a better pad for track use as I got faster I am now using the Hawk blue and black pads which give better stoping power but are not for street use because they need to be warmed up before they work well.
