I used my OEMs up somewhere around 24ishk miles, never warped. Track days twice a year and a daily I5 commute ate them up (ask BDF how bad they were). I went to the EBCs and it made a real world difference. 32,000 miles of the same type of use and the EBC rotors still looked fresh. Of all the pads I tried/wore out the EBC pads worked the best and gave the best feed back Think 150s hard on the binders into turn one. Stock rotors and Corbonne Loraines faded bad at 130s, and had a long break in period where they just felt wooden and rain did them no favors. Galfer pads felt tinny at the lever, I didn't run them to death. If/when I have another C14 my priorities will be easy, swat the flies when I install the ZX14TBs, full AreaP exhaust, PCV, tune, and EBC rotors and pads. And of course my fav set of tires with a 55 profile tire out back.
