this is gonna be long. i had warpage at 17k miles, rotors were turned and once again at 24k miles there was evidence of warpage. instead of getting those turned i went ahead and installed the dba 4000 6x6 wiper slots. so far they seem to be holding up but i've only got about 1000 miles on them i think...one thing i noticed with my pads when i changed them was very uneven wear from the piston side to the floating side. the piston side was an easy 0.100" thinner than the floating side. obvious of slider pin lube problems. so i am thinking that may have something to do with the warpage with the pad contacting the rotor not giving it a chance to let the heat full escape. either that or just simple material issues. anyhow good luck!
