Several brake pads on the market boast 'ceramic' technology. DS1.11 is the real thing. It is based upon a chemical family known as Siloxanes. Unlike carbon based materials, siloxane chains do not decompose at high temperatures and so DS1.11 keeps on working up to the highest temperatures a brake pad could ever see. That means it won't fade and has excellent life, the best in the Ferodo Racing range. Moreover the performance remains exactly the same throughout the pad's (long) life. It is formulated to provide a very flat friction profile at a medium/high level of friction. The pad compression is very low, always, and so pedal travel is short and consistent. The main characteristics of DS1.11 are:

High coefficient of friction at all speeds and temperatures
Excellent life of pad and disc
High initial bite
Predictability and control because of the unvarying torque output
Low off-brake drag/Excellent release
Unvarying performance throughout pad life
Firm pedal. Always
