My gf keeps warping the rotors on her 2000 civic EX. I just had them turned, and installed new pads about 1000 miles ago, and they are already warped again (Bad). I've searched the civic forum already, but I know you guys are harder on your brakes than most. So which rotors have you had the best experience with? Brembo Blanks?

 

Probably not warped.... did you bed the pads in?

 

I've had problems in the past when having rotors turned. They never lasted as long as new blanks for some reason. Brembo Blanks are fine.
However the longest lasting rotors I've owned where cryogenically treated:

Also be sure that it's not misuse of your rotors. Stopping real hard then parking it without giving your brakes time to cool can warp or crack your rotors. Also admit to yourself that it could be you, not your girlfriend, who is hard on rotors... it's ok, we all are on occasion.
