I went to fabric shop bought some thin foam and black marine vinyl. You can take your old as a stencil and make it a bit bigger you have about half an to an ich where you can pinch it in. Mine came off my roof wasnt clean and used a weak adhesive.
Carbotech XP10's are great on the race Z, not hard on rotors either. I could buy pads like Project Mu's locally but instead go to the extra expense of importing the XP10's, good people to deal with too.
