Visually - highest quality rotors I've seen, and a cheap price
We recently replaced both cars with common mass produced "premium" rotors; after only 15k miles both cars exhibit the warpy pulsating feel. I know this isn't actually warping, but rather binder cement sticking unevenly, causing uneven friction. The thing is the factory rotors lasted many times this, and never ever felt this bad. I believe this has to do with the molecular structure of how these are cast. This is why it is amazing to find European made, high quality rotors dirt cheap.
