I'm sorry but there is no way that a replacement rotor should cost over $150. This is the one thing (ok, maybe there's more than only one) that pisses me off about the GTO. C5 Corvettes can get replacement rotors from NAPA for $25. Why should there not be an inexpensive rotor for the GTO? Before you go saying that the NAPA rotors are crap, keep in mind that the T1 guys use them. At that price, they're practically disposable for them. On the street, they last just as long as the stock rotors.
Someone please find a decently priced (<$75) replacement rotor before mine need to be replaced.
If a $25 rotor lasts a year and a $200 rotor lasts 3 years (doubtful) which is less expensive in the long run? I could replace the cheap ones 2-3 times a year if I had to before spending $600-800 on rotors.
If your paying $25 for a replacement rotor, 1) you don't care about performace or quality, and 2) you just bought saftey equipment for your car that was made in China, for around $5 including shipping.
