PCCB problems ?

Having talked to some people who expressed being disappointed with Porsche P.C.C.B. (noting Ferrari owners with similar problems on cost, performance and wear), has anyone any experience with System ST ( www.systemst.com ) ? They claim to have improved performance, lower cost and better wear characterstics on CFRC Carbon Ceramic Brakes than the OEM systems on offer, and are working with some OEM's now but offer systems for a number of cars (Porsche and Ferrari included amongst others). Any feedback anyone ?
