The Napa United brand pads and rotors meet BEEP and D3EA testing and are the same as AC Delco Durastop brand but pads are not the same as OE GM pads quality ,sometimes noisier.The rotors are the same under all three brands.I've bought a United rotor when we only had 1 left on our shelf and the United and Delco parts matched ,identicle on every marking . I've used the Delco pads in Semi-metallic and Ceramic on several cars of my own and they perform well for DD . I presently have Raybestos front rotors on my A4 with the only issue being the hats and edge have rusted more than Zimmermans but not as bad as most cheaper rotors. Actually they rust less than some rotors I've seen on new GM product. I would recommend any of those 3 for daily drivers and performance slotted rotors are available in some of the Raybestos and Delco applications but I'm unsure if Napa offers those ,also not sure if they are sourced the same. I have seen some of the Delco branded come with outsourced pads from ABS Friction or AP in the package on just a few applications instead of being made by Raybestos. That was in the past and could have changed by now.
