if you are just a daily driver, slotted/drilled rotors will actually decrease the stop power of your car.
Unless you ride the brakes for long periods of time you won't see the benefits of venting the gasses.
Just get some new rotors (if needed) you can get oem style brembos cheap from tirerack.com and some really good pads.TRD
, EBC green stuf, Axxis Ultimate are all good brands. I have EBC with brembo rotors, and my stopping distance from 60 is about 90-100 feet, you can activate the ABS on drive pavement if you jam down hard enough, and I've had a couple of high speed stops from 130+ down to 80 in about 1-2 seconds
