Pretty sure I warped my rotors

ResIpsa

Another way of fixing this problem is getting a set of track pads and driving on the street for about a week.

I had horrible brake judder (aka warped rotors) on my G35 which I cured with a set of Porterfield R4 pads. On the street (when cold), the pads are abrasive and act in the same way as a brake lathe. After a week my rotors were shiny metal and when I switched back to my street pads the judder was gone.

There are some downsides to this method...

1. Track pads are very noisy. They don't squeal they howl. You will learn to time stop lights and use your parking brake to avoid embarrassing your self.

2. Track pads are very dirty. You thought early model brembo's were dirty? They were nothing compared to a track pad. And the brake dust pits the paint on your wheels.

3. Track pads are expensive. Considering that a brake lathe cost only around $50.

Come to think of it, unless you plan on tracking your car this is a bad idea.
