I replace my rotors with Powerstop drilled and slotted rotors. I purchased them from "Brakemotive" on eBay. They were actually cheaper than stock replacement rotors. For pads, I went with Wagner Thermoquiet Ceramic pads. They stop far better than stock, have zero noise, and almost zero brake dust.
I also have experience with the Powerstop brake pads that they usually sell as a package deal with the rotors. I bought a set for my wife's car because she has a very heavy foot. They do stop as good as the Wagners, but the have a tremendous amount of brake dust. I had them on her car for almost a year before I bought mine, that's why I decided to try the Wagner Thermoquiet pads instead of the Powerstop pads, and I'm VERY glad that I did!
Also: make damn sure that you use a heavy duty thread locker like Loctite on the caliper bracket bolts!! I had an accident about 5 years later because a caliper bolt backed out while I was cruising on the highway. I had pretty major damage, destroyed a wheel and tire, busted a shock and ripped a brake hose off. But it could have been MUCH worse if I had failed to maintain control when the wheel exploded. When the caliper came loose it rubbed on the inside of the wheel and cut the wheel open like a tin can.
