I used the rockauto POWERSTOP rotor/pad kit for my wife's fusion and they have performed just as well as OEM. Looks like you also need to order brake grease and the hardware, too. Don't reuse the old springs, retainers, slide boots, ect...
You need to buy my Baer BBK. [hihi] It would be a sweet upgrade for you. I would recommend EBC yellowstuff pads for the back, with some Centric smooth rotors. When it comes to pricing for brake hardware, Rockauto is a great place to start, but also check Ebay since there are a ton of solid sellers on there.
