A GT endurance compound built for 12-hour-plus racing, where holding a consistent pedal over a long stint matters more than peak bite.
These are the compounds we stock for the Sumitomo 4-pot — WRX / 300ZX / Skyline Turbo whose published friction and operating temperature come closest to Circo M220. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
