Review on ACDelco 18A257A Advantage Non Coated Front by Daniel Fung

I bought these ACDelco rotors thinking they were a little better than the rotors I could buy at local auto parts stores; but I was wrong! After 4 months of very light riding they warped like any other cheap rotor. I spun the wheels very carefully as Chevy instructs and they still warped. I bought a set of Raybestos rotors for my wife's 4Runner and they are running great after almost a year, but this is a 1995 Lumina that I commute to and from work every day and I didn't want to spend an extra $15 or $20 for good rotors. live and learn
