I replaced my rotors on my truck about every 60k miles. Every other time i change the brake pads. These rotors are great, dont make noise. They dont create much dust with their respective brake pads, I dont need to turn them or anything. Just remove the old ones, slap the new ones on, new brake pads, and you are done. Will buy again? This was my second time buying them for my old truck great price, customer service and fast shipping!
