The compound
Circo M111.
A circuit compound aimed at cars with ABS, with an unusually wide friction range. The breadth is deliberate — an ABS system does better with a pad whose friction changes predictably across temperature than with one that simply bites hardest.
Operating range180–780°C
Friction µ0.31–0.49

These are the compounds we stock for the Mazda MX5 (NA/NB/NC/ND) whose published friction and operating temperature come closest to Circo M111. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
