Centric, like many other suppliers, have more than one level of product. Moog has their premium stuff and also sells a budget line called Quick Steer. AC Delco has their Professional line and their Advantage line. Gates sells their quality belts and also the Roadmax economy belts. And so on.
Centric Posi-Quiet brake pads have proven to me to be a quality product.
That’s not to say I haven’t ever used the C-tek pads and rotors on a customer’s car. I just don’t warranty them against noise and dust and offer a shorter warranty.
