You won't stop faster with different brakes. You'll get more initial torque, and perhaps easier modulation, with high-performance pads. A very agressive pad like the Hawk HP+ will give much grabbier brakes than stock, if you like that feeling. However, in a flat-out panic stop, Stazi's kit will keep you on the ABS just as well as your brakes. You just won't stop faster with bigger rotors unless you are fading your stock pads.
A lot of people upgrade the whole system and claim something made a huge difference when it was really something else. People go to slotted rotors and Hawk pads and claim it was the slots: it wasn't. People get SS hoses and say they make a huge difference: they don't. It was flushing the fluid for the installation that made the biggest difference. If you want to be glued to the windshield when you tap the pedal, highly agressive pads on non-slotted rotors are just as torquey as slotted. But they won't stop your car faster under street conditions.
Slotted rotors do heat up your pads faster in the wet, but that's because they wear them faster. I've always brushed the brake occassionally when driving in the wet, and it's safer and cheaper than slotted rotors.
So it's fine to like a very agressive pedal feel that makes it easy to brake hard, quickly - but it's a lot of money to pay for not really improving your stopping disatance. And what kind of pads did you use when you went slotted?
