At least a year or so ago Carbotech will put any of their compounds on a set of shoes. I purchased Rockauto shoes and removed the material before sending them to in. As to keeping them cool I will take a picture of what an EP/ITS backing plate looks like after having a several holes cut to allow heat to dissipate. I ran steel drums due the amount of heat generated, I think with the holes cut I could have used aluminum drums instead.
