About 8 months ago when I had my front brakes serviced, I had the rotors replaced. Since money was tight at the time, I opted for the economy rotor it hope it wouldn't bite me in the ***.

It didn't really, but in 8 months my car warped the hell out of them. Luckily they were covered under a 1 year warrenty and I got them replaced for free. This time I told them to take the difference and put the best rotor they could offer me on the car.

So all in all, I upgraded my rotors with free labor, and the cost of the el cheapo rotors were put against my new ones. I wish I had some brand names to toss out there, but I don't yet. I got a fresh warrenty on the new ones too.

Moral of the story, don't go with the cheap brand of rotor unless you have some sort of fetish for replacing them every 8 months to a year.

Which Bonneville was that on?

id guess on the 96 since the 89 is "retired"

It was on the '96...but none the less I think the h-body for multiple generations is notorious for this problem.

ive heard that somewhere too. do you torque your wheels? cuz that is supposedly very important as in the warping part, but it should always be done anyways

It'* a problem on the W body as well. On my '96 Cutlass I had the front rotors replaced one time, and not even two years later I had the brakes looked at and they told me I needed all four rotors even though the front ones were not even two years old and had never been turned.

On the cheap rotors I was unable to warp them, however they did have heat cracking.

I'm impressed by either the ability of some here to find even cheaper rotors than I had or to warp rotors when I can't.

I've yet to warp a set, and I'm anything but easy on the car.
