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
Pad life'Low wear'. No numeric figure published.

These are the compounds we stock for the Wilwood Superlite 7416 / 7420 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.
Project Mu H20
Very close200–800°Cµ 0.42–0.44
A sprint and flying-lap compound used in GT and NASCAR classes.
Matched on published friction and operating temperature.
From $525WinmaX W5
Very close100–750°Cµ 0.40–0.43
WinmaX’s standard circuit model, and the default club racing and rally choice in the range.
Matched on published friction and operating temperature.
From $405Project Mu H21
Partial match200–850°C
Circuit and endurance racing. Project Mu rate it as kind to the rotor with long pad life.
Matched on published operating temperature only — one of the two brands doesn’t publish a friction figure, so this is a weaker comparison.
