i wonder if maybe u got a bad set of rotors or are extremely hard on them or maybe didn't break them in properly...i have no warpage that i can feel and i have nearly 14k miles on mine

i followed the included instructions to break them in slowly and stop easy on them when they are cold for the first couple stops or so and i've never had a problem...in fact when i first put them on i used to lock the front right wheel when stopping until i got better tires
