These Power Stop brakes are very good. Z36 carbon fiber and ceramic brake pads are ready to go. I bought more of these for durability and confidence that they will work when I need to hit the brakes. SS washers fit well. Purchase extra pad lube as the lube pack you receive will not be enough. Perforated, slotted and zinc plated rotors along with ceramic pads ensure quiet braking and they are so smooth. Finish ensures maximum cooling and protects against rust and corrosion
