My front rotors are warped again and I'd like a recommendation on an aftermarket rotor that holds up better than the stock rotors.

Warped Rotors

What kind of mileage did you get out of your rotors.Mine warped at about 12,000 miles on my 03 Baja.I think they should add some cooling air ducts for the front rotors.To help cool them babys down.

About that pulsation while braking. It frequently gets blamed on warped rotors. The rotors will have to be replaced but it is for another reason. Hot spots. Thermal judder is caused when the friction material, (rotor), has heat cycled unevenly. The metal at that specific location on the rotor has been tempered and now has a different hardness.
What's happening is: After a hard application of the brakes and the car comes to a complete stop, the brake rotors must cool evenly. The metal where the pads are locked onto will not cool evenly. That is where you will get a hot-spot.
Try creeping after a stop, at least hard ones, just enough to keep the pads moving so rotors can cool some.
