DS1.11

The DS1.11 has a lower mu than the DS3.12 at all temperatures and can be characterized as a moderate mu pad vs. other endurance racing compounds. They require more pedal force than the DS3.12, and they have a slightly declining torque curve as temperatures rise. As they get hotter and you dive deeper into a turn, you may feel like you need to push a little harder on the brake pedal to elicit the same response (which is a feel many drivers actually prefer). Some drivers feel that the DS1.11 is more controllable on street tires than DS3.12 since ABS cannot be activated as easily. It will last a fairly long time vs. many other pad compounds on the market but does not last quite as long as the DS3.12. They are very gentle on discs at track temperatures when a proper pad transfer layer is maintained. The DS1.11 also has an outstanding max temp and fade resistance, just not quite as high as 3.12. We’re not aware of anyone who has faded them, and most people differentiate between the DS1.11 and DS3.12 based on feel.

Below are the official compound descriptions from Ferodo Racing Italy. Please note that the primary value of these graphs is to compare the Ferodo Racing compounds against each other. Comparing the absolute numbers below to published numbers from other manufacturers is of little value, and would be akin to comparing engine dyno graphs from different dyno types (Dynojet vs. Mustang Dyno, etc.). Again, if you’re unsure which compound is right for your needs, please contact us for a recommendation.
