DS3000 is the FERODO RACING compound that has set the braking standard from race one back in the 1998 season. DS3000 has contributed to countless wins and podium positions in many Touring car and GT championships around the world. In addition to its reduced bedding in time (approximately 50 percent quicker than other materials), the main characteristics of the DS3000 are:
Very High coefficient of friction (0,54) at all speeds and temperatures
High initial bite
Predictability and control because of the unvarying torque output
Low off-brake drag
When using DS3000 on lighter racing cars lower brake pressures will be required to achieve the required deceleration.
The graph relates the friction level of DS3000 to vehicle speed and to the temperature at the pad/disc interface.

DS3000 Plus 03 was developed by FERODO for severe braking conditions, where high friction is required at extreme temperatures. The material has an exceptionally high coefficient of friction (0.72) is whilst maintaining the same gently rising toque profile as DS3000 and great initial bite. This compound is used in Touring car, Stockcar, GT, Indy Light, Formula Nippon, Formula 3000, DTC and many other international Series. The main characteristics of DS3000 Plus 03 are:
Exceptionally high coefficient of friction (0,59) at all speeds and temperatures
No fade
Predictability in all conditions
Good release
When using DS3000plus03 on lighter racing cars, lower brake pressures will be required to achieve the required deceleration.

While maintaining the essential characteristics of the DS3000 family, FERODO "Endurance" material has been formulated to provide extended pad/rotor life in events of three to six hours in length. The main characteristics of DS3000 Endurance are:
Exceptionally high coefficient of friction (0,46) at all speeds and temperatures
No fade
Predictability in all conditions
Good release
Whilst lower in overall friction level than DS3000 and 'Plus' DS3000 Endurance has the same excellent modulation as its sister compounds whilst maintaining an excellent bite.

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 (0,50) 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
DS1.11 is recommended for use in A1GP, FIA GT, Touring Car, Formula cars and Group N.

DS2.11 is the sister compound to DS1.11. It is based on the same siloxane technology and shares many of DS1.11's characteristics (unvarying performance, short pedal, excellent control) but has some additional features, notably it's extremely high bit and friction coefficient. Pad life is slightly lower than DS1.11. It is especially recommended for rally (WRC race proven), but is suitable for any other application where very high friction, bit and a rising torque profile are desired.
High coefficient of friction (max 0,62) at all speeds and temperatures
Very high initial bite
Excellent disc life and condition
No fade. Strong torque profile.
Good pad life
Low off-brake drag/Excellent release
Unvarying performance throughout pad life
Firm pedal. Always
DS2.11 is recommended for rally applications and sprint races.

die DS1 en DS2 zullen wel meer hardcore zijn...trouwens hoe hoger het coefficient of friction nummer is des te harder de bite? en dus remschijf vreter?
