PolyMatrix Brake Pads
Wilwood has many types of brake pad compounds designed specifically for racing. It is important to analyze braking requirements and
select the proper pads. Experimentation is often necessary to determine the correct compound for a particular application.

POLYMATRIX “A” COMPOUND POLYMATRIX “Q” COMPOUND
Heat Range: Low to X-High, Torque: X-High Heat Range: Low to Medium, Torque: Medium
“A” compound delivers an immediate cold response with the high- Ceramic-enhanced compound is ideally suited for aluminum ro-
est friction values at all temperatures. Engineered for severe duty tors. Provides smooth engagement, long service life, quick recovery
oval track race applications which require immediate high response and high fade resistance.

POLYMATRIX “CM” COMPOUND
POLYMATRIX “B” COMPOUND Heat Range: Medium To High
Heat Range: High, Torque: High
With quick warm-up, high friction and fade free performance at Best compound for titanium rotors. Medium to high friction sin-
