CIRCO S83 is a low-metallic carbon compound for performance street driving and entry-level track days, and this set suits the Lucas / Girling 18/4 RRS-19 18/4 RRS-25 20 mm. It is also used on the rear axle of race cars, where its repeatable friction and bite that eases off at the end of a stop help prevent rear lock-up. CIRCO quotes a friction coefficient of 0.32-0.36 across a 0-600°C operating range, with good modulation and low to medium friction.
