They are what they say they are...
The Power Stop Z23 Evolution Ceramic Brake Pads have nearly stopped my Challenger's awful brake dust problem, without sacrificing stopping power and the quietness of operation. These pads are head and shoulders better than the OEM Brembo pads. No more daily finish rinsing and drying, and no more squealing when brakes are applied. I would recommend them for anyone wanting an almost completely trouble-free quality brake pad.
Excellent brakes that are well worth the price
Last time I installed these brakes and rotors they lasted me 5-6 years and were quiet, reliable and low dust during their use. Easy to install and gave me real peace of mind knowing that I had quality parts for something so important for my daily driver.
