Ferodo DS2500 is amongst the foremost high performance track day pads�in the business. It is also suitable for some light duty front and many rear pure race applications. It offers excellent refinement for such a high performance pad. The main characteristics of DS2500 are: Track day & light race use for all vehicle types Road style refinement but with race material ability to withstand heat with respect to life and � Average friction coefficient of 0.42 over working temperature range of 20�-500�C  DS3000 is the FERODO RACING�compound that has set the braking standard from 1998. It has contributed to countless wins and podium positions in many Touring car, rally & GT championships around the world. The main characteristics of DS3000 are: Heavy duty all-round material choice Short bedding time Multiple applications including touring car, rally, Group N, single seat, hill-climb Average friction coefficient 0.48 over working temperature range of 200�-650�C Several brake pads on the market boast �ceramic� technology. Ferodo 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: Heavy duty endurance material Applications � touring car, GT, single seat Average friction coefficient 0.46 over working temperature range of 200�-700�C Long life Very kind to discs
