This is true. When it comes to the Napa fully coated rotors, even though Napa lists tighter runout specs on thier site, I believe they are the same rotors as the Raybestos Element3 (formerly RPTs). One member went further noting the part # number similarly in the two products as posted
here. The Napas are significantly more expensive.
I also installed some Wagner E coated rotors as posted
here. They're nice, however as commented on in the link the coating does not cover the exposed rotor surfaces not touched by pads. Centric would be similar. Rust not much of issue here, so no biggie. I've got a vehicle with standard AAP Wearever uncoated rotors and they've held up nicely, no significant rust. The Wagner E coated are more expensive than Raybestos Element3.
This is great info, thank you. That's what throws me off...if the NAPA coated rotors are the same as the Element3 and supplied by Raybestos, I can buy the Raybestos parts at exactly half the cost. However, the Element3 quote a runout of 0.004" max and the NAPA are 0.002" max. Does that mean Raybestos sends the ones with better tolerance to NAPA, and the ones that didn't machine up so well in the Element3 line? If they truly are the same I can just use the Raybestos parts at much lower cost, but it's hard to know what is what these days.
