These rotors seem to be good. They replaced a really warped set, so of course they are much better.In combination with the Hawk LTS pads the rotors provide strong stops with good feel on my 2003 GMC Safari.They do make some faint noise while driving and amusing space-ship noises under hard braking.I am hoping that they last longer than the OEM rotors that I have replaced several times, but it is too soon to tell.A year and a half later I am very pleased. These rotors are still working just like you would want them too. Much better than the OEM parts.
