RW> That happened to my Z28, early on, maybe at 65k. The factory rotors were   
   RW> notoriously thin and any amount of agressive brake use warped them right   
   RW> now. I'll bet every agressive driver will have experienced that in the   
   RW> 4th   
   RW> generation F-bodies.   
      
   I have noticed that using good ceramic pads helps in many ways, too.    
   Generates less heat on the rotors, last longer, and much less brake dust.     
      
   I also use ceramic pads on the Harley.   
      
   RW> I replaced those with an aftermarket rotor made by GM but sold for   
   RW> $150 less per/pair than the same rotor that was on it. These were also   
   RW> drilled and slotted. I also replaced the old pads with Titanium pads.   
   RW>    
   RW> The car now has better brakes than it came with from the factory. Which   
   RW> allows the driver to drive deeper into a curve or corner and brake later,   
   RW> increasing the speed through a road course.   
   RW>    
   RW> Put new drilled and sloted rotors up front, sand the pads on a flat   
   RW> surface if they have high and low spots in them. You'll be happy with the   
   RW> results.   
      
   I had considered putting the drilled/slotted rotors on, but some people say   
   they aren't as good for braking.  I have never tried them, myself.     
      
   If my current rotors warp early again, I will try the drilled/slotted ones.
