Real-world improvement,or just cool looks?

Lol true, but I got it all as a package deal, and its not just the loss of surface area from the rotors I'm wondering about, and not really how it would perform on my vehicle, but real world experience going from stock to a set up similar to what I have sitting in the garage. Not too worried about numbers or theories, but the difference it made on your cars. I do understand what you are saying, tho. Polished valve covers always made a huge increase in my hp! Pishta, like you mentioned about how I drive, I kind of doubt aftermarket brakes would make that much difference because since I almost always have kids with me, my driving has calmed down dramatically.
