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 Brembo GT 6-pot B24 (RD54) 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.
