I have a 01 a6 2.7t and i was looking to get new front rotors. Ive already determined that they are 321mm but i cant figure out the offset of my current rotors? when i measure the rotor hat (on both front rotors) i get a measurement of 19mm which i know is really weird considering they are either suppose to be 16.7mm or 22.7mm! They have been resurfaced once or twice now. Maybe they were once 22.7mm but after they resurfaced them now they are 19mm? which offset should i go with? cuz my brakes are really acting up and i dont have the money to take it to a shop!

 

anybody any ideas?
