    StopTech Drilled And Slotted
    Great rotors, well designed and high quality. Had my mechanic install them, along with new ceramic brake pads (Akebono). I also purchased the recommended stainless steel hoses. We have a large hill we are always negotiating, putting a lot of pressure on the rotors. These high performance rotors are the perfect solution for our driving needs and safety. The touch, feel and responsiveness are incredible.
