Delivers smooth, consistent engagement at all temperatures and pedal pressures. POLYMATRIX “Q” COMPOUND Heat Range: Low to Medium, Torque: Medium Ceramic-enhanced compound is ideally suited for aluminum rotors. Provides smooth engagement, long service life, quick recovery, and high fade-resistance. COMPOSITION METALLIC “CM" COMPOUND Heat Range: High, Torque: Medium )RUPXODWLRQLVVSHFL¿FDOO\IRUXVHZLWK6XSHU$OOR\URWRUV Compound offers high friction throughout temperature range.
“A” compound delivers an immediate cold response with the highest friction values at all temperatures. Engineered for severe-duty oval track race applications that require immediate high response at low temperatures.
POLYMATRIX “B” COMPOUND Heat Range: High, Torque: High
With quick warm-up, high friction, and fade-free performance at high temperatures, “B” is the best choice for sprints on pave- ment or dirt tracks with extreme braking. BP-10 (“SMART PADS”) COMPOUND Heat Range: Medium to High, Torque: Light to Medium A medium to high-temp compound, low-dust characteristics, and the low-temperature response of a street pad. Use on dirt track cars with vented iron rotors, club sport, and track day racers. POLYMATRIX BP-20 ("SMART PADS") COMPOUND Heat Range: Medium to X-High, Torque: Light to Medium Provides increased friction levels with extended temperature range over BP-10. Ideal for heavy braking on dirt tracks, and hobby and sportsman asphalt racing. POLYMATRIX BP-30 ("SMART PADS") COMPOUND Heat Range: Medium to X-High, Torque: Light to Medium Long-wearing pad in the middle temperature ranges with moderate wear in sustained high-heat conditions.
