Ferodo DSUNO brake pads for AP Racing CP9660 calipers are a heavy-duty semi-endurance compound designed for track, race and high-performance motorsport use. Designed for the CP9660 / CP3905 pad profile, these pads use an 18mm thickness and 54mm pad depth, making them suitable for AP Racing Pro5000R CP9660 six-piston calipers.
DSUNO is built for drivers who want strong braking performance with a controllable pedal feel. Ferodo lists the compound with an average friction coefficient of 0.48 across a working temperature range of 200°C–750°C, making it suitable for repeated heavy braking, touring car, GT, single-seater, rally and track car applications.
Compared with DS2500, DSUNO offers a higher friction level and wider temperature range, making it more suitable for dedicated track use. Compared with DS3000, DSUNO is more focused on controllable torque output, long life and being kind to discs, making it a strong option for drivers who want race-level performance without an overly aggressive feel.
