The compound
Circo M119.
A carbon-metallic compound built for rally and circuit work, and the standout in the Circo range for short events. It publishes 0.48–0.51 friction from a 50°C floor — near race-compound bite that is already working on a cold first lap. Circo describe it as more forgiving to drive than M127.

These are the compounds we stock for the AP CP5200 family / Brembo 4-pot B52 (D50) whose published friction and operating temperature come closest to Circo M119. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
