The compound
Circo SC17.
The mildest compound Circo make, aimed at street and 4WD use. It works from ambient and tops out below 500°C, which makes it a road pad that tolerates the occasional hard drive rather than a track pad that tolerates the road.
Operating range0–490°C
Friction µ0.32–0.35
Cross-brand equivalents
Run something similar.
These are the compounds we stock for the Toyota 86 / Subaru BRZ whose published friction and operating temperature come closest to Circo SC17. They are a starting point for switching brands — not a guarantee of identical feel, because each manufacturer measures friction on their own equipment.
