Review on Enhanced Performance Kit: Power Stop K1588 Front Z23 Carbon Fiber Brake Pads with Drilled & Slotted Brake Rotors by Jon Robertson

I've had these discs and pads on my 2007 Pontiac Grand Prix for eighteen months now and haven't had a single problem. With standard rotors, it seemed like I had to rotate or replace them every few months due to pulsation. I had absolutely no ripple or issues with these rotors and pads. The worst I can say about them is that when you apply the brake lightly, there is a very light feel in the pedal that could come from the slots. These rotors and pads work much better than the original equipment. When you step on the brakes, you stop instantly - without fading.
