Performance brake shoes?

Does anyone know a company that makes performance shoes for our rear brakes, and a place online to buy? It seems the companies such as Hawk, EBC, and PFC that I know make good pads don't make shoes, or at least not for the cherokee.

Thanks, Kristoffer

Porterfield Racing in Costa Mesa, California. They used to make a carbon composite shoe for the XJ, if not they can reline some old shoes for you with that material...
