EBC has a new Greenstuff pad compound called VR4. I you get the Greenstuff pads make sure they are the new VR4. Apparently this new VR4 compound cools better so that the rotors will not warp. I think the Greenstuff pads I have on the front on my Countour that warped the EBC Sport Grooved rotors are the old compound. I am in contact by email with EBC and will let you know what they do for me.
