I have the next in line rotors, the 400 series I believe for the 80 series. It is a harder material can take more agressive pads currently only comes in slotted not crossed drilled(unless this changed). It also has heat paint(3 colors) to see if the owner has over heated them thus putting them out of warranty. Material is harder, by how much i do not know(nothing in reading material and al could not give me an answer when I e-mailed him months ago). works great, lock them up with the abs off, very little fade with 100 series pads. I personally will not go to a more agressive pad does what I need. later robbie
