Review on K2948 Evolution Drilled Slotted Ceramic by Keith Barra

It was a process for everything to stop creaking. They are great and look great on my Camaro SS. but - DO NOT install without first grinding (spinning) the rotors. A rotor at your local store will cost you $20-$30. If you don't, you'll sound like a Greyhound bus every time you stop at a stop light. Once that's done, there's no drop in noise and smooth braking all the way. I would highly recommend them to anyone. but they require more installation effort than originally thought.
