If you put on the EBC Greenstuff's and their black oxide
rotors, they have an extended warranty of some sort. That tells me the pads and rotors were engineered to be compatible. HOWEVER, rotors are currently only available for the NA Cruiser.
Although I now have 40k and pads/rotors are okay, I plan on the EBC combo come Spring. The OEM discs are too soft (and rusted out!!).
