The compound
Circo M207E.
The endurance version of M207, tuned for 12-hour-plus racing: slightly lower peak friction in exchange for a lower floor and more consistency over distance. Circo publish a wear figure of roughly 0.5mm per hour in full race conditions — the only quantified pad-life number any of our brands provide.
Operating range150–900°C
Friction µ0.42–0.49
Pad lifePUBLISHED NUMERIC FIGURE: 'wear rates of around 0.5mm per hour in full race conditions' when temperatures are in a good range. This is the only numeric wear figure published for either brand.
Cross-brand equivalents
Run something similar.
These are the compounds we stock for the Mazda RX8 front whose published friction and operating temperature come closest to Circo M207E. 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 PCR09
Very close300–800°Cµ 0.42–0.55
Project Mu’s Club Racer. A strong trackday pad, but with a 300°C floor it is the range’s worst choice for a cold first lap.
Matched on published friction and operating temperature.
From $359Project Mu HC+
Very close0–800°Cµ 0.43–0.58
The street-and-track all-rounder: usable from cold and rated to 800°C, which is why it suits sprints with no warm-up lap.
