Review on Enhanced Performance Brake Kit: Power Stop K5879 Z23 Carbon Fiber Brake Pads with Drilled & Slotted Front and Rear Brake Rotors by Justin Santiago

Rotors have a good finish, Pads come with all new SS hardware. Installed by mechanic, driven over 1000 miles. A noise will be heard, similar to the initial wear indicator of the rotor part spring. The mechanic who also disassembled the passenger found that there was no drag and the ground clearance was good. We don't think the sipes rub against the pads at low speeds. The noise occurs both when braking and when coasting at low speeds. In addition, the rear pads can be smaller than the original or the rear rotors can additionally be drilled towards the center, since the braking material left on the rotor does not cover the entire surface of the disc. **update noise noted, a little wear on the wheel bearing, car has 90k miles now, I have replaced both front wheel bearings, one side was around 60k + the other when these brakes were fitted around 80k. The car brakes decently, not much better than the original, I still think I'd be better off with solid original rotors.
