I have the Performance Pack, The Brakes and Rotor from the Factory are the best you can get in my humble opinion(unless you want wilkwoods). If anything I would use stock rotors and upgrade you pads, if you looking to improve stopping. If you looking for esthetics then I guess those will work.
I have road coursed my car, several times, and trust me when I say if I had those rotors(depicted in website picture) I would crack them easily. I have a friend with Carbotech pads and uses stock rotors, his has more bite than my factory pads, but also are noisier when stopping on the street. I am thinking about upgrading the pads... but for all around performance I can not beat the Factory Performance Pads.
Our rotors are reverse hat to aid in cooling them, and have more mass to help dissipate the heat.
My 2 cents
