				Rep Power: 18  | Sure about that number? We had some plates ground a while back and took some measurements of re-ground used and brand new OE plates. We found a new set of OE plate to be about 12 Ra (micro-inches) on average. Our guy got the used plates to an average of 8 Ra. The rough correlation between the RMS and Ra is around 11%. So our measurements for the stock plate would roughly be 13 RMS. They look to good to be as bad as your measurement would suggest.
