Purchased October 2017. Nice set and easy to install. At first I was satisfied with the product. After 1.5 years I had to replace the rear brake discs and pads, not because of wear but because of the rusting on the brake disc that forms on the braking surface in any wet/rainy weather. wipe off As a result, under heavy braking, the rotor became heavily glazed, pitted and pulsated. The durability of the product did not convince me. The front rotors seem fine. Not sure if the rear rotors were a bad batch? Update: I now had to swap the front rotors due to waviness and glazing. upset.
